I know this has been up before but I´m still confused.
On this site http://cnn.cn/shop/htc-tytn-c-277_279.html
they sell antenna for the hermes gps.
As we know Hermes has an internal gps but without the internal antenna that is necessary...
So has anyone installed such hardware?
It would certainly be interesting to know if with the external antenna the GPS would work. Looking at it I think it might, the only problem I can think of would be the device recognising the GPS. Great find!! Good on you!!

Looking at the product page on this antenna there are som pictures with it installed.
It attaches to the connector behind the rubber protector next to the camera.
Is'nt this the connector for external radio antenna?
Or is there any smart electronics that connects this connector to the internal gps module?

I wondered the same thing.
This has been discussed to death so many times. Most recently, this exact antenna was discussed in the Hermes Accessories section of this forum (use search, I'm not going to do it for you).
Here's the FACTS!
1) There is some of the circuitry (hardware) for a GPS in a hermes. Some is missing. This is most likely due to the chips that the hermes uses having multiple built in functions. One function was needed so they used a chip that just happened to have part of a gps built in.
2) Adding the rest of the gps harware isn't practical and has a 99.9% chance of destroying the device even if you are highly experienced in working with surface mount components.
3) Even if you added the antenna, etc. successfully there is no firmware to drive it. You still need to write everything from scratch and make the firmware work with the rest of the pda/phone. You would have to do this without benefit of having any existing source code for the pda. Good Luck
4) Assuming you managed to do all this, and plugged in this antenna, you would have a gps that needed this big ugly antenna wired to the phone. So why not just spend the $50 and buy a bluetooth gps that works without wires and doesn't need the phone modified?
5) The store selling this antenna have stated to queries (see other threads) that this antenna is for use when using an EXTERNAL gps with the hermes. In other words, some bluetooth and wired gps units that work with the hermes have an external antenna jack so that if they are used in poor conditions this antenna can be used to boost the range by placing the antenna outside the vehicle, etc.
6) You cannot use this antenna plugged into the hermes external antenna jack. it will probably destroy the phones radio instantly and permanently. In fact, its a very bad idea to use any external antenna with any radio that wasn't specifically designed for the radio. There are many reports of frying the radio by using 'universal' cell phone antennas.
In conclusion.... GIVE IT UP!
There is no usable gps in the hermes!

ok then, anyhow very misleading pictures on that site then.
why would i install a wire to my phone if i have gps on bluetooth. makes no sense.
Ps. I knew this was discussed earlier but I wanted uptade on if someone tried it recently.

deach01 is correct. I agree the people selling this antenna should make it MUCH clearer as to its purpose.
To the best of my knowledge all development work has stopped, on getting the partial GPS functionality of the chip to work on the Hermes for the reasons deach01 states - it's just not practcal, and as said already the bluetooth receivers work well without major surgery to the Hermes.

Total BS! That site actually shows a picture of that antenna plugged into the back of the Hermes, talk about misleading!

If they used a chip and it had GPS as a bonus and they just ignored it, why then would the go through the troubleb of adding an external antennal connection and mod the device housing to accomandate it?
The external antenna connection is NOT for GPS. Its for the cell phone radio.
Don't believe me?
Go ahead, plug in an antenna!
Hope you can communicate by smoke signals as your cell radio transmitter final amplifier toasts itself.
THERE IS NO WORKING GPS IN A HERMES!
Do you really think that HTC would build in a feature like GPS and NOT market it?
An expensive option, Kaiser!
An expensive option is to go for Kaiser(soon to be at&t 8925 ?)
Does anyone know for sure that at&t is NOT gonna kill GPS on Kaiser? Just heard today it has pass thru FCC (
http://gizmodo.com/gadgets/windows-mobile/-283367.php )
As soon as the Kaiser comes out over here I'm going to get one, it's like the WM version of the N95.
Hello
the mainboard of the UNI has a slot free where a GPS receiver could be placed. Has anybody the information which chip could be pluged in there to have the UNI build in GPS enabled?
Regards Highc
Quite impossible
hi highc,
the missing chip is a RFR6250. This builds up the GPS backend for MSM6250 chipset.
But there will be no chance to use it, even with the chip soldered.
What is missing, is an ugly hacked radio rom to access the hardware in a proper way.
So if you're a genuis in hacking binaries, you're welcome
Cheers,
scholbert
I recently had to replace my speaker on a verizon xv6700
To my surprise i think the cameria flash board has a GPS reciever chip layed out but no components. It looks like the board is missing the GPS chip (6 pin IC with 4 pin metal cover/shield) itself and what looks like a serial level shifter (10 pin IC)
Tracing it briefly i can only seem to find a DATA IN (gps to phone) I was hoping to locate the DATA OUT (for programming the gps unit) and once located, send some test data to the GPS port and capture it on an oscilliscope - this would confirm that this is infact a real GPS chip layout and they never put the chip on due to cost or some other factor.
This means once we figure the pinouts you can get any old GPS reciever chip and solder it onto this board and enable real GPS
has anyone else noticed this??
here is a picture of the board i am refering to

Is there anything I need to do except turning GPS on in settings to get GPS working? My Nexus 7 can never find GPS signal, even when I am outside. Any APP to test it?
Apparently rebooting nexus 7 worked. Not sure why though, I didn't change anything settings either.
Sent from my Nexus 7 using xda app-developers app
GPS Status is a good app to see what the GPS is doing.
Sent from my Nexus 7
The nexus 7 have no data connection do download AGPS data, be sure to connect to a WiFi network and try using apps like GPS status to try and get a lock. And as long as you are near a windows, no need to go out, the gos chip in the nexus 7 is pretty sensitive.
Will the next nexus have a longer screen?
Hello, i found the "Bug" on my Nexus 7 - and it was Hardware.
There was simple no Connection between the GPS Antenna in the Backcover and the GPS Receiver on the Mainboard.
How to fix this? Pull off the Backcover, locate the GPS Antenna. Then locate the GPS Antenna Contacts on the MAINBOARD, and bend them upwards a bit, so that they will connect to the Metall Pads in the Backcover.
Have Fun!

Thank you! My GPS had been so reliable up until a few weeks ago that I figured the radio was damaged. Never thought to check those contact pins... I could see sattelites and get a fix, but the signal was so noisy that it wouldn't detect any movement, and it usually placed me a half mile away from my actual location.
Saw this post last night, popped the back off, gently bent all of those contacts up a degree or two, and BAM! All my radios are working very well again. :good:
Last week, I tried to use the GPS during a flight, but as the windows were very small it was difficult for gps to find satellites.
I'm wondering where the GPS antenna is located on mother board or elsewhere.
I found the info for my Nexus 4, but not for 10.
Do you know that ?
