Hello everybody, I was thinking update the radio of my car, is a Toyota Avensis T25, year 2004. The radio I was thinking buy because is suitable for the car (image bellow). It brings TDA7851 MOSFET and for Antena controller is NXP6686 (I think the Manufacturer is (Chinese) Philps).
The Sound of radio is good or bad? The output sound is horrible with TDA?
I'm strict with Audio, so, I don't know what I will buy.
Help
Thanks a lot.

yes, it's good...by chinese standards.
7850/7851 better than 7388 they used in the past.
and 6686 is a good FM chip.

I ordered it one month ago, has arrived to my home and is now mounted in my car. I notice the qualaty of audio is a litle smaller, but is good.
Now I have another problem. The radio says support the 3G/4G Modem USB, I have the USB Dongle, but, the car can´t acess the Mobile Data. I tried with PPP Widget 2, the widget says that I am connect but no internet when I open Google Chrome, for example.
With the same USB Dougle I connected with my Galaxy S7 and I have internet with PPP Widget 3.
You can help me more one time?
Thanks

no android 8.0 unit supports 4G natively as data connection. Even their own dongles are hotspot connection only.
there are some dongles that work but 3G only.
8.1 apparently they do support 3G/4G, some even have built-in sim card slots for direct data connection.
but those are px30 units as far as i know, not px5
Stop wasting your time with 4G Dongles.
Tether. Simple.

NXP Semiconductor (formerly Philips Semiconductor) is a DUTCH company. Not Chinese.
These are OK radio receivers. They used to be impossible to deal with, but they're not half bad now that the programming manual has leaked out. Sound is decent, however, reception could be better. I suspect that the reception issues are more due to the chinese module that they are installed in than the receiver itself.
The TDA7851 is from STMicroelectronics, Dutch registered, Swiss headquartered.
Note that both of these components are things you would find in OEM and **mainstream** aftermarket car radios.
But be aware that there is a lot more to a good quality sound than just having a couple of components that are good by themselves. Like a chain, its only as strong as its weakest link. So like i said, put a crummy RF circuit on a TEF6686, and the reception will be less than stellar. Put a crummy analog audio mixer in front of the TDA7851 or too small of a capacitor, and your sound quality will suffer.

Hi, you tried this?
1. goes to wifi settings and connect the dongle
2. hotspot & tethering
3. wi-fi hotspot
4. Active Hotspot
5. press return button to the home
Maybe it's a signal, 3g at least...

Provided the head unit is compatible by manufacturer, you can get more quality out of the audio with a modified mcu update.

just about to buy
1. does it have wifi ?
2. WM5 - so push would work
3. Anyone know who to unlock (does it use c550 unlocker) ?
rgds
no Wifi
Push enabled
no idea how to unlock
the keypad is bad, the TV is pretty poor....unless you want to watch in a wide open space near a town centre....
the DAB radio is pretty good.
tx. a pity about the wifi
is the tv service limited to virgin only or after an unlock any tv can be streamed?

will work on any network. It uses DVB like freeview not GPRS
It must post back to Virgin or something so they can charge PAYG customers the monthly rate, it (the TV) may not work with another network's SIM in it.
The TV service will work regardless of SIM.
However it uses cryptkey encryption, similar to satellite services.
Therefore, every so often Virgin/BTmovio will change the crypt code and the TV will stop. When this happens you will need to reinsert the virgin chip until the TV re-opens, after which you can put in your other chip.
Note:1. for PAYG you will have to start paying after 3 months, except for BBC1 which is always open.
2. DAB radio will always work (well, whilst DAB is still broadcast in the UK )
rgds
NO A2DP bluetooth audio (manual says it does, but Virgin must have removed it for some reason) :-(
Lobster feedback
Had mine for a few weeks now - very pleased for the money, replacing a trusty but declining C500. SIM unlocked (paid) and running on BT mobile (Vodafone).
TV is watchable (just); radio is great; otherwise an excellent value up to date smartphone, albeit with some minor (to me) keypad handling issues.
Best features:
- radio
- screen quality
- price
A few small niggles:
- no case yet and the plastic over-screen gets scratched easily
- ITV1 won't register now (says Virgin bites not available, try later)
- bit of a pain having to plug the wired headset in as an antenna (which seems to get tangled easily - looking for a way to keep this tidy)
Amazed there's such little interest in the phone at this price...
with the tv i dont like the fact there is no full screen view or at least not that i can find...
the radio is great. the tv channels are very limited but hey do the trick now and then
My views on Lobby.
I would also have liked the ability to screen capture from TV to use as Wallpaper.
Great phone, though. I like the bulkiness. It's also different to the norm. Very clear screen & talk. easy to get around. pretty awesome DAB quality. TV is watchable if really bored.
Surprisingly good piccys from a 1.3. Very adequate. They blow up to monitor size ..... just.
Downloaded Emails from Hotmail with ease.
Definitely better than any phone I've had to date.
Nice feature being able to record sound from external source and use as a ringtone.
My lobby over the last 5 months
I got this phone in December - Virgin pay monthly contract.
Good points
- Screen resolution
- Battery life (normal use)
- Lots of great applications can be installed
- DAB radio - this is the best feature.
Bad Points
- Non really
- TV not great - few channels
This is my 3rd Smartphone (MPX200, MDA Compact) and cannot fault it. It is was a flip-phone (clam shell) then I'd be even happier. Still, you can't have it all.
I personally own a 3g WCDMA version of zpad, which i believe it is the same as g tablet from hardware aspect. except with more memory and internal 3g card.
i opened up the zpad and found inside is a mini-pci of Ericsson F3307 WCDMA 3g card for the 3G connection. I knew the linux driver F3307 and F3507g (with built-in GPS) share the same driver source code file, It will be nice to have built-in GPS and therefore I decided to give it a try.
I bought a second hand F3507g and plug into the zpad to replace the original F3307. It looks really good at beginning, the cellphone antenna indicator show full signal strength, When I look into wireless & network setting -> Mobile network -> Access Point Name. I was able to see a full list of provider that available, which means it is working. The SMS works, I even received few message while i was play around with F3507g.
Unfortunately, for unknow reason, i wasn't able to get connect with 3G network, I am not a hardware expert, so not exactly sure why APN is available but just can't get connected.
and as for GPS, nothing show in the setting menu to indicate the availability of GPS.
nothing really got work actaully, but it seems if some know system better can get both 3G and GPS work relatively easy!
anyway, for these who want a 3G on their g tablet, Ericsson F3307 maybe a way to go! the 3g WCDMA firmwares are available here in China.

I belive we are missing the connector for the module which would rquire delicate soldering

The connector is not soldered on, but the soldering isn't that bad since the connector is a through-hole component and the pads are quite large.
That's true, it didn't seems too difficult to solder these. With little patient and some skill, it shall not too difficult to put Ericsson F3307 into the g tablet and get a 3G connection. The 3G firmware is also available in Chinese z-pad forum, and i believe that TNT lite also use 3G firmware.
What really bother me is why F3507g doesn't work in 3G while I was able to receive SMS and get a full list of APN. and I have no idea how to enable the GPS which make this modification all senseless to me.

ROM
What ROM are you currently running?
Looking around here, i see that plenty of people have more then one phone.
But i don't see any way to make them work together.
How possible would it be to make them connect with wifi / bluetooth?
Have them both ring when a phone-call comes in and make it not matter which you pick up?
Stay connected to the internet on both phones when one loses signal? (living on the border between Belgium and the Netherlands, when one has internet, the other one probably doesn't)
Share audio with 1 Bluetooth headset?
Do you know a way to make any of these happen?

You could pair the two devices together using Bluetooth but that would be for transferring files and other stuff I suppose. I don't think it's possible to have them both ring when a phone-call comes in and have it not matter which phone you answer. To get internet on both phones most people tether phone A's internet connection and create a wireless hotspot and then connect phone B to the hotspot. But if one looses signal then other one would loose internet signal as well, if there is no signal in an area there is no signal, and both devices will be without service. And what do you mean by share audio with 1 Bluetooth headset? You could pair both devices with the same Bluetooth headset if that's what your talking about (For example phone A is paired with Bluetooth headset A and phone B is paired with Bluetooth headset A also).

The problem is that i live on the border between 2 country's, so if i'm in Belgium, i have to set my Belgian phone to tether wifi, my dutch phone to connect to it, and a few hours later il be in the Netherlands and i need to tether my Belgian phone to my dutch one. If i forget to disconnect it, and i leave the country, both phones will not have internet. Then i am home, and i have to select my home wifi. I cross the border 2 or 4 times a day. Doing it manually is a pain.
Both my phones are paired to my headset, but that old thing only connects with one phone at the time.could fix it by buying a new one. But i like the sound of the one i have now.
But correct my if i'm wrong, but the hardware should be capable of much better cooperation between phones. I just can't find software to do stuff. is there any?

I'm not sure about the data issue but you could use Google voice and set that up to ring both phones...

That wouldn't work. I would have to give all my friends and contacts a US phone number.They wouldn't ever call me.
But i did figure out a way to properly share internet. Tasker!
While (not roaming) and (not at home(check with gps? Bluetooth of computer in range? certain cell tower? other?)) and (other phone nearby (check with Bluetooth)) tether internet.
Else, connect to wifi.
I guess i have some scripting to do and i should buy a new headset. That way i can answer both phones with the same Bluetooth headset, and share internet.
What is more battery efficient? Bluetooth or WiFi tethering?
it seems the nexus 10 has a broadcom BCM43241 chip which supports FM radio, i read on other forums that there might be issues as the chip might not be grounded with the headphones ground so some antenna connectivity issue, i tried spirit fm but doesn't seem to work, is there any development going on to enable the FM some how? can any1 confirm if it will ever be possible to make use of the FM in that chip using some custom kernel or software?

This is * definitely * not the answer you're looking for - but have you checked out the TuneIn Radio app? I KNOW it will only work when on wifi, not giving you the actual FM experience. But I've found that pretty much any terrestrial radio station I listen that has a simultaneous web broadcast, TuneIn Radio also carries it.
I'm sure I'm not telling you anything new, but you know..."just in case". :laugh:

yes im aware of online radio stations but just trying to dig in whats the situation with nexus 10 as it has the supporting chip, no idea if its antenna is connected and also no idea if the drivers r available in the OS, i also emailed spirit fm developer today so lets hope he can help out coz it would be great to use FM directly rather than wifi which might not be available everywhere and also the device doesnt have 3g.
google if ur reading this, atleast make some external 3g dongle or put in support for same and also if there is a FM chip, then make use of it
i got the reply from mike reid
" No, no FM antenna pin connection. "
so i guess make this a sticky or so that officially nexus 10 will never support FM, in spite of it having the chip

Who is Mike Reid?
Also, people said before that the Nexus 4, although having a 4G chip (or LTE?), was not able to use it due to lack of connection to the chip (or lack of connection to an antenna). And now the Nexus 4 has 4G (or LTE) by some software mod.

he is the developer for spirit FM app, LTE is different coz the antenna for 3g is connected to same chip that has 3g as well as LTE so a mod could simply do that but FM is different, they might have simply never bothered with it but if some1 thinks he can solve this, well and good.
i wonder what they use the barometer chip for also and if it even works
some1 needs to be up the hardware and verify the antenna connectivity, all it would take is a connection from the chip to the headphone jack.
"chip has a specific FM 88-108 MHz antenna pin"
I got my postcard and email regarding the class action settlement, so I might as well take the $17. But I already have a GPS dongle -- it showed up out of the blue a few months ago as I recall.
I haven't used it as all since I have no need for GPS with the way I use the tablet (GPS is much more useful on my phone), but something about the way the message was worded made me wonder if the dongle also has a WiFi antenna in it. The standard WiFi reception is definitely weak, although again it isn't a huge deal for me (I notice it most when connecting to hotel networks that are weak to begin with). So does the dongle do anything for WiFi?
Short answer, no.
