I just bought an MEX-BT2500 and had it installed - all at Circuit City, for the Americans on this forum.
Since I literally *just* got it, I will give an initial impression and then update this in a few days probably with some more info.
INITIAL IMPRESSION
Well, it looks nice. The buttons have blue LEDs. But that's not very important. Pairing it with the Hermes was pretty painless, you just turn it off and then hold the Equalizer/Bluetooth button >7 seconds. The passcode is, of course, 0000. It has three separate Bluetooth icons - one for it being off/on/discoverable, one for hands-free being connected, and one for A2DP being connected.
When re-pairing after turning it off or something, the A2DP mode does not reconnect automatically. I've tried pressing 6 (Pause) and that made it reconnect. Maybe there are other ways of doing it, I don't know.
I am still experimenting with the A2DP settings to figure out what sounds best - I am using the Microsoft stack, so I'm not expecting miracles here - so far, it sounds OK at BitPool/MaxBitPool = 58 and Joint Stereo = 1. Contrary to popular belief, Joint Stereo is NOT mono, but I have yet to determine whether the Microsoft stack thinks that. I just need to play the right song. I read somewhere on this forum that increasing BitPool/MaxBitPool to 72 while keeping Joint Stereo on sounds good, so I'll try that later.
I will try the hands-free mode later on as well. Updates to follow.
UPDATE 1: More on A2DP (and a bit of hands-free)
I set both of the BitPool values to 72 and enabled Joint Stereo. It works well. The sound is most definitely stereo, and the quality is a lot better than what it was with a lower BitPool and Joint Stereo off. I've never tried the Widcomm stack, so I can't compare it to that. I also tried hands-free calling, but it did not work at all. That turned out to be an issue with the ROM (because it no longer worked with my HT820 either), which has since been resolved by flashing a different ROM. One extremely disappointing thing is that it looks like, for making calls, you can only initiate a redial from the device. I haven't looked into that too much yet.
UPDATE 2: Hands-free
I still haven't been able to make it do anything but redial for initiating calls, but the call quality appears to be quite good, both for the person on the other end and for me. I have to say, I'm impressed by that, especially since the Parrot MK6000 apparently has a huge separate dual microphone that you have to mount in order to get clarity.
One thing that has started to annoy me is the beeping when I turn off my car. Apparently it's to remind me to take off the faceplate, but I don't always want to do that and it pretty damn annoying. I don't believe there is a way to turn that off. You can turn off other beeps, but not that one.
UPDATE 3: A2DP again
The wireless stereo really does work well! The Hermes is able to handle receiving Internet radio streams (www.di.fm in my case) and piping them through A2DP just fine using MortPlayer. Speaking of which, AVRCP works well. Play/pause, previous, and next buttons all work, but with a slight (<1 sec) delay, which is caused by something other than the BT2500 because the same delay occurs with the Motorola HT820. It's either an issue with MortPlayer or the Microsoft stack - I don't know which one since that is the only combination I've used that supports AVRCP.
One thing I have yet to try is receiving a call while listening to music. I will try to do it tomorrow and see what happens.
I've had the MEX-BT5000 (the BT2500's predecessor) since January & use it with my Wizard. I haven't had any issues with A2DP connections -- I've paired it only once when I installed the headunit.
The only time I have to reconnect is if the Sony powers up without my Wizard in range -- the next time I power up the Sony, it'll connect to the Wizard's hands-free profile, but not in A2DP. To reconnect A2DP, open up the Wizard's BT connections screen, select the MEX-BT5000 device, and right-click "Set as Wireless Stereo".

Im fitting a BT5000 today in my new car. What car did you install yours in?
Ive fitted a new head unit to a vauxhall corsa before but never needed to use the smart cable for steering whell controls...is it dead easy?
P.S: the new car is a 2003 vauxhall astra
Does the BT5000 let you do voice dial through the Hermes/Wizard, or does it also just support last number redial? So far, I haven't been able to get it to do anything but redial for call initiation.

Mine is a 2002 Mitsubishi Diamante -- I had to get a $60 translation unit to interface the steering wheel controls to the headunit. Installing the translation unit took some doing -- they're a bit tricky to program.

Haven't tried voicedial -- I've got Voice Command 1.6 installed on the Wizard, so I think it'd work. I'll give it a try tomorrow.
Quick report back, had a right bastard of a time installing it LOL!
Vauxhall cables are deliberatly CRAPPY, i had to swap over two of the wires because the unit was not keeping the time or radio stations when i switched off the ignition. I also purchased a smart lead to enable the steering wheel controls.
Finally got it working, works an absolute DREAM with both A2DP and handsfree.
I am also thinking of getting the BT2500, but my big problem with it is the 'redial' problem. Apparently the BT5000 can download and store 50 numbers but doesn't allow for voicedial, (I've heard anyways)...
Trancecoder: Did you ever find something to trick the phone into launching voicedialing when a bluetooth redial was activated? What about the 1-6 buttons, can they be programmed for speeddials like the BT5000 ??
JamesManios - I don't believe the BT2500 downloads any contact info whatsoever, so those keys won't be able to be programmed. As for the redial vs voice dial issue, I haven't experimented much with it, so if there is a way to make it speed dial, I haven't found it yet.
Trancecoder: Thanks for the reply, how are you liking the unit now that you've had it for a while.
As an idea for dialing I was thinking of making an app to maybe accomplish it, but some of it I don't know how to do yet...
My idea was, have the app pole every 200msec or so and see if the phone has started dialing (that I pretty much know how to do), then see if you are connected to the bluetooth handsfree (don't know how to do that just yet)... then the program can assume that if you are dialing AND in the car (because you are connected), then you must be using the redial... STOP the redial and launch the VoiceDialing app...
It leads to some questions, like would the Stereo drop the BT connection and therefore the voice prompt would be from the phone speaker and using the phone mic and NOT the stereo...
I currently have this (which works very well), but not as clean as the stereo ... but I'm not sure I want to lose CallID and VoiceDial... to buy this unit.

ive had a bmw m3 and the bluetooth sucks in it my infiniti much better. i always use my jawbone though. I may need to pick this one up.

The unit's pros outweigh its cons, at least for me personally. I receive a lot more calls than I make while driving, so the dialing issue is not a big deal for me. The person on the other end can definitely hear background noise, but they can still hear me pretty well when I have my windows open and driving ~50MPH. The unit also plays MP3 CDs, which is nice because I have some from when I was using my old MP3 CD player. A2DP quality is good, although occasionally there is a drop out for about half a second. Sometimes it happens 20 minutes into driving, sometimes not at all, so I have no idea what's causing it. Overall, I'm satisfied with it.
One thing I noticed is that when I press the Hermes button 5 (mapped to Cyberon Voice Commander) while fully connected to the BT2500, the "Say command" prompt goes out through the Hermes' speaker and not the BT2500. That may cause additional problems if you want to try and create a software fix for the auto-redial.
That Vitebo website is full of Engrish! "THE FRESH PET OF CAR ARTICLE" - what does that mean?
Ya, that website is pretty brutal, unfortunately the manual is similar but I got it finally figured it out (I hope)
I decided against the Sony and bought a none BT headunit, thanks for all the info though.
Had mine for 8 months now...
Excellent unit. I had BMW factory fit bluetooth in my old car, this is much clearer (VW Passat).
I used mune with an Artemis, and now an Elf/Touch...
It doesn't download a phonebook, so the only dialing it can do is redial last number - but just use PocketCm and dial with your finger!
Quality is good - I have found, however, that A2DP streaming breaks up unless I use Coreplayer, which is 100% perfect... and yes, pressing '6' a coupl eof times toggles on the bluetooth stereo on the device, which is good, because otherwise, I wouldn't be able to hear tomtom instructions if I had the radio on!
Sound quality all round is excellent - just a shame it dosn't have a steering-wheel mounted remote instead of the useless IR one...
I was wondering if anyone could help with this problem. My SGS II connects with my in built (Ford) car system, its does everything it should apart from that it can not display the call list (in or out). This was also the problem on my SGS on stock roms until I installed CM7 and then the call lists showed up perfectly. Is it the case that Samsung roms are putting the call logs in a different place that cannot be seen by the car system, if so would it be easy to change this or do I have to wait until a CM rom is made for the SGS II.
SGS II as well as SGS has a very gig problems with BT in car on stock ROM. I had SGS before and there was a problems BT constantly drops in AUDI car system. Temporarily it was solved by BT Fix from the market but finaly solved only coming to a custom ROM (all of them solving that). Now Having SGS II It is total disaster in AUDI - first it constantly drops BT connection and even more - if I'm talking by phone during being connecting to BT, connection failed BUT after call finished phone crushed down and it takes 10 second pushing power button to get it back :-( And then in phone all pairings went out! So - do anybody know this case? And waiting for the custom ROM.
I have a Mercedes E-class (new type). No problems at all with the BT. Very quick to connect, and I can control track fw/bw from the steering wheel. No drops. Works with the default music player as well as Spotify. Phonebook transfere is quick.
In terms of functions I also have no any problems but drops and crashes :-(
Ford focus audio bluetooth
Hello,
I have the same issue with the Ford Focus Bluetooth. It plays ans stops all the time. hands-free works great. Did you solve it?
Hello everybody.
the same issue with new Volvo S60. Previously car kit perfectly worked with Nokia E71... As for S2 - I was able to pair the phone and car. But afterwards, connection could be reestablished only if it's initiated from the phone side (I select "My Car" in bluetooth menu of the phone). Without such actions the car is unable to find the device...
Problem was solved for me when last modem was released. Use ROM with XKE2 modem.
Hi all,
Yesterday I have tested SGS2 (LiteROM 1.5) in my BMW E92 LCI and it works really fine so far.
(call, sms, phone adressbook and bluetooth audio streaming).
BMW offers the possibility to connect two phones at the same time.
I successfully connected my nokia business phone for bluetooth call & SGS2 for bluetooth audio streaming only.
SGS2 is the first mobile that I have connected to my car not only displaying title/artist information properly using the default music player,
but also offers good mp3 sound quality over A2DP.
Strange enough, when I use a different music player (e.g. PowerAMP) the title/artist information is not working any longer. Any ideas?
Cheers, Spad
Problem with transmission over car bluetooth
Hi there,
I have a galaxy s2 that used to connect (with no problems) with my alpine CDE-126BT
After I messed around with the service mode for a while trying to crank up the volumes, there is no transmitted voice over the call (the other side can not here me when I'm connected to the car's Bluetooth).
I know that if I reboot the phone all the changes that was done in the service mode would reset to the default settings, it seems to revert back default but I still have the same problem.
Any advice??
Thanks,
David.
So, I'm having a strange issue with my new Note that I can't quite determine where the root cause may be, or if it's a known issue.
If I register my Note with my car as both a phone and an audio device (how the Infiniti nav/stereo works) I can use the Note as a phone fine UNLESS I start an audio app, such as Pandora. Once a2dp audio starts the Note will no longer connect as a phone device, but it works fine for audio.
I had the phone paired with the stock ATT rom but only used it as a phone, so unfortunately, without a restore to stock, I can't tell if the problem exists with the stock rom.
I flashed to flappjaxxx's rom (which I love) the same day I setup the phone to run Pandora via Bluetooth and that's when I started seeing the problem.
I also see some random connect/reconnects that seem a bit more than usual.
So, I can't say there's a correlation, or if this is a known ICS beta issue or what, but I'm hoping it is and that it's not a design flaw
Way I see it it's either:
1. Flashing to any ICS beta rom has the problem, currently?
2. It's in flappjaxxx's build (doubtful)
3. It's user error...(possible )
4. It's an app issue (ie. Pandora is causing the problem?)
Anyone have any thoughts, suggestions or insights? I've done some searching but haven't found this exact issue yet on any posts.
Thanks!
I have a Kenwood DNX9960 in my Avalanche. It connects also for phone and for streaming media. I can be streaming media from either the stock music player or an internet site like pandora or TuneIn and my calls will automatically come through. When the call ends it goes right back to streaming.
It autoconnects to both as long as my phone is in range when I turn on the kenwood. I did have an issue at first where it would not autoconnect. I deleted the pairing from both my phone and headunit. Then when I repaired I paid close attention to check any boxes to "Always" allow connection and I haven't had any issues since.
I understand the normal pairing process, I've had several phones before that worked fine prior to the Note. So, I'm thinking that it is probably a corrupt bluetooth db... I'm going to be reflashing to Flaps new rom and we'll see how that does
Is there a way to delete the pairing from the nav? I would try that
Sent from my SAMSUNG-SGH-I717 using xda premium
There is. I've tried it all, on both sides of the pairing.
I've reflashed the phone to the B6 from FJ, still no joy. The pairing db was new (so no chance of corruption on the phone) and the pairing deleted on the device.
It seems to be a problem with the phone switching between a2dp and phone bt. When a call comes in (while playing say Pandora over bt) the audio cuts out and then the car shows "disconnected" and then "connection failed" if trying to reconnect to the Note as a phone (ie hitting the phone button in the car).
I'm hoping it's the current ICS build. Just have no way to really know. Hoping some other folks will have seen the same issue.
Going to run some tests with different audio sources and see if the behavior is the same.
Well things seem to be working now, for no obvious reason I'll have to assume that the reflash resolved the issue, I just can't tell for sure why it didn't work immediately after. I think it's due to deleting the old pairing on the car and not shutting down the vehicle.
Cheers.
BT connections
I have similar problem connecting to van audio system (vauxhall). After some experimentation it appears to be an ICS problem, if I reflash my note with gingerbread I have seamless connections for both audio and phone. As soon as I upgrade even with offical ICS bluetooth connections become problematic, I can pair but not autoconnect. Tried samsung and they just "fob off" with it's an incompatable device. Until a bug fix is issued it appears as though it's a choic of staying with gingerbread and have a working system or ICS and no handsfree.
I haven't seen anyone else post this yet so I'm hoping someone can help me out. I have a Bluetooth speaker in my car that works fine on stock or on kit Kat roms. But on every lollipop rom I've tried, the audio through the Bluetooth is slightly slowed down (resulting in everything sounded a little lower) and kind of choppy.
The audio plays fine through the phones speaker or through a headset, it's only on Bluetooth that this happens.
Any body else having this problem? Any suggestions?
Same issue here.
I think it may be the speaker I'm using, because I had the same issue when I connected my tablet to it that is also running lollipop. I need to find a different Bluetooth device and see if the problem persists.

I was doing a search on this issue myself, which brought me here. It's actually only one speaker I have that does this, and it's the newest BT device I have. It's the HDMX Rave portable BT speaker. It worked fine with the KK ROMs I was using at the time I got it, but ever since updating to LP, only that speaker of all the BT audio devices I own does that.
Weird...
Similar Issue
Hi,
I've also experienced this, although it seems my Bluetooth plays much worse than yours. It's slow for a bit, then choppy and breaks up, then it'll speed up the music to get back to where it should be. It renders Bluetooth music completely unusable.
I've found:
High CPU usage causes this in KK (skydragon) for me. The high-usage culprit is the netd module, not sure if that's relevant.
I've flashed Jasmine Lollipop (5.0.11) lots of different ways, with several different modems, and it still has this issue.
It doesn't seem to depend on the app, as it happens with the default music app and with Spotify (192 Kbps).
It happens on both of my Bluetooth devices, a cheapo portable speaker and my nicer car stereo. I don't know the BT versions they use.
Disabling WiFi helps a little, disabling data does nothing.
Anyone have any workarounds?
i had the same problem when connecting to my car speaker.
funny thing is some days it works great, and other days all of a sudden it just plays all slow. anyone got fix?
So I've been doing some more tinkering. Turning off WiFi will fix the issue for my "dumb" bluetooth speaker (it's a pair button and a power switch only), however it will only fix the issue for the first ~3 minutes on my Clarion car stereo (with all sw updates). I've disabled literally every Bluetooth service, activity, provider, and responder that isn't essential for A2DP connections. I'm able to access the hidden menu item for Bluetooth testing, but I don't really know how to use it. If someone has directions for that I'd gladly put my phone through the paces.
I have this little problem with my new Huawei.
(I have a Mate 10 Pro, couldn't find a section for that specific model)
Whenever I connect it to my car or Bluetooth headphones, the audio from my phone will randomly switch from my car speakers or my headphones to the phone speakers. The only way to get it outputting audio through the Bluetooth device again, is by reseting my Bluetooth connection. However, it does this every time and its driving me insane.
Can someone help me with this? Thanks in advance.
Hello
Try to remove all bluetooth devices associated on your phone.
Then associate Bluetooth with your car
Do not try to associate other devices for the moment.
Then try to listen music from your car to speakers of your car
If it's ok, then associate other devices and try again to watch if all is allright
This is a known bug that has been around since release, there is nothing you could do to fix it.
This is by far worst Bluetooth implementation I ever saw in android
On top of Your problem mine stops sending call logs to the car randomly and restart or re pair are only option to mend it
So strange ! I'have never had problems with bluetooth audio with my car !
Except if decide to receive the conversations sound on my Bluetooth smartwach.
Android don't like to have 2 bluetooth devices connected for sound at the same time
All the top cell phones are having blue tooth issues...just google it. It is not unique to this phone.
I have the same phone and issue and this is still not fixed ! Has someone found a workaround?
My mate 10 Pro works fine in my car, no issues at all. It works fine on Android Auto too. Yet in my parents' car, Android Auto won't work at all; I just get a black screen.
I guess these problems are often between two specific pieces of hardware rather than a general fault with the phone, so quite difficult for manufacturers like Huawei to fix everything. But if I had my parents' car, I'd be pretty pissed!
This is a known issue with EMUI and it has to do with EMUI killing processes in the background in the name of battery optimization. If your music player is in the background or your screen is turned off, EMUI will situationally kill or freeze bluetooth/audio related processes.
If rooted, use either Titanium Backup or Service Disabler to freeze/disable the Power Genius app. This app is responsible for EMUI's battery optimization measures (but the battery life on my Mediapad improved when I disabled it). If not rooted, you might or might not be able to do this via adb.
Other solutions include plugging in a charger, or leaving your screen on.
(edit - you have to reboot after disabling Power Genius, merely disabling it will not immediately change anything)
