I noticed this item for sale and was suprised because I was under the impression that it was determined that GPS didn't work on the Hermes due to technical limitations even when using a Trinity radio. Go figure.
http://cnn.cn/shop/8525tytnhermes-antenna-p-1615.html
pof has been alreayd pmed about this yesturday. waiting for a reply from him to see if he is willing to buy to see if it'll work. if you read more closely you would find the gps is missing the antenna and it requires lost of work to get one in there. this might be able to go in where u put a gsm antenna but lets wait for pof to see what he says.
aha... thanks for the update.

Would be excellent although the Hermes GPS is not Sirf III....
Anyone tried this one?
got pm from pof. the antenna will only help bluetooth gps and not the internal gps. oh well. thanx to pof for saving us the trouble of buying then finding it wont work.
damn man, i bought that antenna as soon as i saw it up!! soooo... like..... theres nothing i can do with this??
ok, it doesnt seem to work.
but it has to help the internal gps, the way it seems SHOULD function wouldnt make sense to help the bluetooth gps. ive seen many other cable GPS like this one on the internet. anyone else buy this?
I'm not sure I follow the function of the antenna....if it is just helping the bluetooth gps, is it then more of a bluetooth antenna, or does it just do nothing for the 8525?
I thought the bluetooth gps was its own antenna, otherwise what would the purpose of it be? Thanks!
I know this sounds sketchy... I read a post a while back about this port where you can attach antenna. A person working with the GPS project for the Hermes TyTN device discovered this port and connected a different model of antenna from Radio Shack. He went on stating that this port is for GPS. NOT Bluetooth When he connected the other style antenna he noticed both his reception (data,voice) increased along with the number of satellites he could acquire.
This is in one of the threads realated to the GPS. He has pictures and stuff too.
I stand corrected.. This was not found in the development thread of GPS with the HTC TyTN device.. This was in a thread where the person took apart their device and showed different pictures of the ""guts"" I'm trying to find the link for the thread now..
any updates on if this worked or not?
I do remember reading somewhere about how people were trying to physically build in a small GPS device into there 8525.
Although nothing about this antena though.
Makes me wonder if there is an actual built in GPS reciever inside the phone.

No but I think *some* of the hardware necessary is present. Why not just use a bloutooth GPS rather than having one tethered?
if anyone could post an update it would be appreciated...
what i have learned is that the gps antenna posted on cnn.cn is a type that is supposed to amplify and intensify the signal for your bluetooth gps... but this still confuses me. im guessing it boosts the signal for that the bluetooth attempts to pick up, but why am i plugging it into my 8525 then??
i hope there is some sort of use for this paper weight... besides the paper weight.
Theres no way that thing would fit inside a hermes is there?? It looks huge.. the kind of antenna youd need in a hermes is a tiny one shaped to fit into the top of the phone...
That anteanna is simply that.. a gps external antenna.. theres thousands of those available..
you can use it on a gps navigation system with an antenna connector in order to position the antenna for better reception.. like if you have a coated windscreen that gps cant get through you can use that lead round to the sunroof or back window to allow it to gwet signal while still having the gps unit under the windscreen where you can see it..
That thing is a standard GPS antenna.. the one needed would be a tiny thing.. with no wire and a whole load of soldering and work to fit it... it will probably never happen.. certainly not with something off the shelf like that id imagine. (you could maybe strip that down and get at the actual antenna inside.. but i highly doubt it would a)be small enough, b)fit, c) work afterwards or d) be in any way easy enough to acheive.
From the pictures on the site it looks like that thing plugs into the external antenna socket on the hermes.. but that wont give you gps.
It might improve signal quality in the car though..as it will probably work in some way as a GSM antenna.
(Have you tried plugging it in under the litttle rubber cap on the back of the phone as shown and seeing what happens - it may of course blow up the phone since it ISNT designed to go in this hole!)
Bluetooth gps is a lot better...becuase it is wireless...I have the holux 240 (smallest on the market)...and it can pick up signal inside my house
The GPS was investigated already for the TyTn, it will never work. The chip has the GPS capability however, there are many pins tied to ground. It would take major modification to attempt to use the internal GPS.
Use bluetooth like Holux, forget plugging anything into the rear antenna port. You have been warned!
so what is the deal? are you telling me that if i buy this external antenna http://cnn.cn/shop/8525tytnhermes-antenna-p-1615.html a gps application will not work? if not how can i get navigation on my device?
explain to others as it was explained unto you!

if you read carefully, you will finally understand that not having it is not going to deny your hermes a gps app.
External= the outside; outer surface; exterior.
antenna=a conductor by which electromagnetic waves are sent out or received, consisting commonly of a wire or set of wires
therefore external antenna mean outside the unit,
gps application = software for use inside the unit
Options therefore:
1. TyTN + INTERNAL BT antenna + BT gps receiver + gps app = works fine
2. TyTN + INTERNAL BT antenna + BT gps receiver + gps app + External antenna(plugged into little hole on back of TyTn not your butt = works much better (because of better reception).
Therefore, unless you install TOMTOM 6 on your pc and expect it to work on your PPC thats the only way it wont work.
Even easier to understand is this:
Imagine you are in your car and you are driving you want to listen to music(find a route) on the radio(your TyTn). Its easy to find your favorite station(gps sat) as your radio(TyTN) already has an
External antenna if you were to unplug the external antenna then you would only be able to pick up a few stations but the radio would still work.
and to the question of getting navigation on your device, you would a) have to install a gps mapping software(TOMTOM navigator comes to mind) b) have a wired or unwired gps RECEIVER. that is all.
Hope i explained it good enough.
FYI I'm using TomTom navigator 6 and Qstars 32 channel bluetooth receiver on my Hermes and it works just fine, and i dont have an external antenna.
If you need any more help feel free to pm me.
Cheers.

Not quite correct. For the external antenna to improve GPS reception it would need to be plugged into the GPS receiver - not the phone. Plugging it into the phone will be a complete waste of time because the phone does not 'do' GPS. Wired GPS receivers can't be used with the Hermes - it has to be Bluetooth.
So long story short, when attempting to replace the caps for the radio circuit (for the 2nd time since the first time I used ones that weren't quite right) I screwed things up, the headunit still works I just have no radio audio.
Any thoughts on a fix?
I could replace the main board, but I've already done the Audio Mod and then I'd still have to swap the caps on the new one (or live with the lack of treble).
What about a USB FM tuner, maybe something that even has HD radio?
Contact the factory and buy a new radio IC ?

That was plan B, tho it would have to be a whole new main board, was wondering if there was a cheaper and easier solution that might also improve radio reception, seems like maybe one of the DAB/DAB+ adapters would work but there doesn't seem to be a decent software solution for those, at least not one that would be good enough to compete with the standard radio app.

It's not the tuner that is bad, its circuitry on the main board, long story short, I had done the radio audio frequency with caps that werent quite the right value, upon trying to redo it with the correct ones, one of the traces got damaged, so while the tuner part works the circuitry that feeds it via the radio input selection doesn't.
I looked at the DAB solutions, but we don't have DAB or DAB+ here (our digitial/HD radio is a completely different spec for which there are no USB modules). I could use a DAB/DAB+ module for just the FM, but from what I have seen none of the software parts of the solutions look very attractive compared to the stock radio app especially considering I wont have the added features of DAB/DAB+ like the artwork, song titles (the stations over here are really poor in terms of their RDS data), etc.

I see, what part of the world are you in ?
The app could eaily be altered, but you cant just tune into the FM signal, it only works if the DAB signal drops out.
Get a new motherboard then, I dont think theyre expensive.

US, in that case it seems like a DAB solution wouldn't work for my need, if it only switches to FM has a fall back and needs a DAB signal initially.
I ordered one, but I believe it's defective so I am now waiting to hear back from them, would have loved a standalone option that would have improved on the appalling reception the standard tuner gets.

No DAB in US, no HD radio solution by any MTCB manufacturers ? No USB HD radio solution ?
Theres something wrong if your tuner gets bad reception, do you have an OEM antenna booster in your car ?

Yeah it sucks, I would have even settled for a satellite radio option, not that I can find a USB solution for US HD radio spec, I think its a really limited market, plus the phone carriers (main android market) aren't particularly found of FM/HD radio being available on android (or other) devices.
No the car is old (1999) so just the standard antenna, on the previous board it worked (wasn't has good as OEM radio, but acceptable, I tried some of the aftermarket boosters and they made things worse). With the new main board all I get is static and it wont auto tune to even the most local stations.

The age of your car isnt that relevant - have you actually checked the base of your antenna for a power lead ?
Can you post links to the "boosters" youve tried or similar ?

The antenna is a standard antenna, I've had numerous other aftermarket radios with no issues before including my Ouku unit and my previous JY unit worked it just wasn't as good as OEM.
I used one off ebay and then another direct from Joying.

I think we are getting off topic here, I'm not looking for a way to improve radio reception, the unit wasn't great (compared to the OEM radio) but it was acceptable. Just looking for another option for FM radio reception, seems like there isn't one if you aren't in a DAB/DAB+ market area.

If installing an external HD Radio add-on is something you have interest in, consider checking out the Directed Electronics HD Car Connect Radio DMHD10001. These add on units can be had for $30 US or less on ebay and connect to your head unit via the AUX in RCA audio connections or via FM modulation. That said, I recommend using the RCA connections to anyone, as the FM modulation will usually have lessor overall audio quality. Please note that these specific Directed Electronics HD Radio Units need to have a ground jumper wire soldered from one or both of the tops of the gold RCA jacks to the black DC Ground in order to fix the over-modulation (distortion) issue. To do this jumper cleanly, remove the case cover and solder the jumper to the 90 degree ground pin at the plug connector. I also recommend drilling some vent holes in the upper case cover to help cool the unit as it does heat up.
Please note that these HD Radio units are only for use in the US (as far as I know), and are best used in areas of the Country that have more than a few HD channels available like here in So Cal. They do work with non HD AM/FM channels too. Some of the pluses are the additionally available music and news content in HD with no monthly fees, somewhat higher sound quality, as well as the overall better sound quality when compared to the built in FM tuners in the current Chinese android head units.
Attached is a pic of the grounding needed to fix the factory over-modulation flaw when using the RCA audio connections.
Moreover, you should be able to find an external satellite radio add-on unit that ties in via the RCA audio in connections if no usb version is available.
Hope this helps...
Your mileage may vary.
Best to all,

Thank you, I was thinking about something like that (obviously via aux in and not FM modulation, since my FM doesn't work). What I would love would be something like this that then had an Android app that could be used to remotely control the unit.
I had an HD radio add on box for a Clarion NX501 years ago, I don't live in a part of the country that has a ton of HD stations and depending on where I drive I don't always have the best coverage, but it is a possibility.

I appreciate the input, but I think there is some confusion over my needs.
I need an external FM tuner (i.e. something USB or the like with an android software solution for tuning). I have two motherboards, one has damaged traces for the radio circuitry so there is no radio audio (BT, streaming apps, etc are fine) the other that was bought has a replacement seems to have a defective tuner or something, I get nothing but static. This isn't an issue with the antenna or anything since prior to the damage on the original motherboard I had acceptable reception.
So to recap, I don't need to improve reception (tho if the replacement tuner offered better SQ or reception that wouldn't be a bad thing). I just need to find a way of getting an FM signal to the unit via USB or Aux in. Something like Rhacy would be good, but I was hoping for something a little more integrated and controllable through an android interface.

Yes, I know what you need, we touched on a new motherboard to fix your problem, I was advising for when you fit your new motherbaord, basically, the FM reception on these units is pretty good, once you have done a few basic things.
But I didnt realise you actually had the motherboard already and your problem is static.
In that case its HIGHLY likely that you simply need to flash the MCU to solve your problem - what device do you have and what MCU version ?
I recently had a similar problem (no radio, just static) and all that was needed was an MCU update, its very common after updating.
It could also be the wrong tuner type is set in factory settings, have you tried playing around with them ?

Thank you for the MCU mentioning, you could be onto something, the new mobo didn't behave exactly like my old one, I had issues trying to get my phone to pair with BT (though that could be due to new MAC address but same BT device name, I didn't work too hard on it since the radio issue was more pressing). But also the buttons on the front acted a little weird, like normally when I have one of the MTC apps open (radio, their music player, etc) if I hit the home button on the front of the unit it would keep that app playing but return me to the home screen, with the new mobo it closes the app like I pressed the back button, have to press the soft home button in the top left of the screen to keep it playing music.
I have the old mobo back in now, I will try and see what the MCU version is on that and then install the new mobo and see if its the same or different and try upgrading it.
I did try all the different options for the radio device under the factory settings menu, but all but one (the original one selected) resulted in just silence rather than static.

You will probably have to try different BT devices in factory settings as well. What MCU version is your new mobo ?
