Share GPS location from HU to phone - MTCD Android Head Units Q&A

Is it possible to automatically update my phone gps location to the same as my HU gps location?
I rarely turn on gps on my phone. Only use it on certain condition. But GPS will takes time to lock especially when I'm inside a building and not moving.
Is there any app that I can install on my HU so that it will update current gps location to my phone, maybe via bluetooth?
Thanks.

Shared GPS Port

Is there a known problem with the shared GPS port on the X7510?
If I use 3dtracking (http://free.3dtracking.net) it just locks up (the app, and sometimes the machine), but it's find on the direct port, but that locks out other GPS apps, eg. TomTom.
Recently I started using Google Latitude, and after a while with TomTom as the focus, it (TomTom) loses the satellite lock, and when I switch to Google Maps it starts with "Initializing GPS" and also picks up nothing. A reset is necessary to get GPS working again.
Anyone else had similar problems?

I'm seeing a similar issue, though no locking.
SatNav programs (TomTom and iGO8) can see the GPS Port on either COM4 or COM5
Spb Weather, which does not have any GPS Port configuration options, so must use the MS GPSID cannot obtain data from the GPS receiver.
Spb Weather can turn the GPS receiver on, as it starts the amber LED flashing, but no data is extracted, and the location query fails. It then fails to turn the GPS off again.
It works fine on the HTC Diamond

[Q] Google Navigation jiggles

Hi!
I'm using my tf in my car as navigation system. I have the direct comparison to my Samsung Galaxy S (SGS) smart phone and I have to say that Google Navigation isn't running smooth for me. When driving through the streets, the displayed position jumps or jiggles from point to point in an interval with about 6 seconds. My SGS can handle this smooth, with the arrow moving in a constant speed over the maps.
First I expected that the TF has a worse GPS module but it seems that the GPS receiving is pretty good with other diagnostic apps. Could it be that Google Navigation runs better on a slower and older device?
How can I fix this problem? I have the newest OTA update from 25th Aug for DE.
thx
Could you try another navigation software? May be its some of the background app/temps.
How are you getting your Map update?
You will need a 3G data to push the maps (unless you have pre-downloaded them first of course).

I activate wlan tethering on my phone and connect the tablet over wlan. Works very good and the map updating is pretty fast. It also possible to listen to webstreams or watch youtube without any problem so I don't expect a problem on the internet connection.
thx for your answer anyway
Can somebody confirm, that it should be possible to have a smooth navigation in google maps navigation? Maybe it is a basically problem with the transformer?

Understood.....
Try this and see if there is any difference:-
Next time you have a WLAN connection on your TF load Google Maps and download a map you would use for a particular journey.
When you next go out try using just your TF (not tethered) and the downloaded map.
Basically at this stage all we are trying to ascertain if the issue is with tethering or map updates.

2 things:
first... I think the beta labs feature to download maps is just for google maps and not google maps navigation. anyway... I make an offline test.
second... Do you mean to make a test without wlan or bluetooth enabled? Right now there must be much wireless traffic in my car:
bluetooth: phone to parrot
bluetooth: tablet to parrot
wlan: phone to tablet
other wireless: parrot wireless steering wheel remote
Maybe something of these disturbs the GPS?
Your phone is cheating. It has an assisted GPS that uses both GPS and cell triangulation to speed up lock and help maintain location when GPS is weak, without cellular your tf has to rely only on a limited GPS chip.

Exactly what I was building up to Ryan.

I have to say that I develop GPS Receiver for space use and I know a little bit about GPS
Anyway AGPS or assisted GPS just speeds up the first fix (as you said) and can fix the position error a very little bit. On weak GPS signal it wont make any difference if you have AGPS or GPS. Both wont work and none would work better or worse. With no GPS signal the AGPS Receiver would only know where the satellites are but thats it and he can't navigate with this info only.
So I don't expect a problem due to the not available AGPS, just to stop the speculation .
Maybe it's a SW thing or the GPS chip is just bad.
Anyway I still don't know if google navigation is running smoth on your tablet?
The Problem is solved...
A Speedometer Widget seems to be the cause:

I uninstalled the widget and Google Maps Navigation runs fluently.
thank you all for helping

Bluetooth GPS app

I wrote an app that tells me time to a starting line where the official start is based on GPS time. My app needs the best location accuracy and the time from the GPS satellites. To get DGPS, I need an external module and for that I bought a Qstarz 100XT which has WAAS capability.
I cannot find an app to interface the module to my phone or tablet. Here is what I have tried and what the problem is:
1) Bluetooth GPS - loss of bluetooth lock without re-acquiring. Totally useless in a race situation.
2) Bluetooth GPS Provider - time reported is system time, not GPS time. I can set the system clock off 5 minutes and all my GPS apps thing the time is off 5 minutes. Totally useless.
3) GPS Mouse - same as #2.
In addition I would really like 5Hz update rate which Bluetooth GPS Provider has but more important is something that works, does not lose lock, and reports the GPS time not the system time.
I have read like 100 posts here on xda and Googled it for hours. I posted on stackoverflow without success.
Does anyone know of an app that really works for interfacing with an external GPS and reports distance and time from the satellites and reacquires when it loses lock?

I use Bluetooth GPS 0.7.5a by Googoo Android in combination with an external GNS5870. This works like a charm for months now, using copilotlive premium, sygic (mock locations activated)

Location on watch

Does anyone know if it's possible to get GPS on the watch without the phone being paired. Everytime I try tracking in s-health it will only track my route if GPS is on on my phone. Similarly in here maps I can't get a location fix if GPS is not turned on my phone.
Sent from my SM-G920F using XDA-Developers mobile app
I know that the LTE version can transmit GPS location without being connected to a smartphone. I'm not sure about the BT only model.

I also have the LTE version. It works but you have to go into the settings and turn on the location in settings. I don't know how it works with BT version. You may want to go in and see if you have location settings.
As far as maps, you may be out of luck. You will still need the phone to send the map to the watch. With the LTE version I can get a map or navigate in standalone because I have a LTE connection to retrieve the data.
Now I did notice one thing. When I am connected to my phone, my S3 gets GPS from the phone and not the watch. The GPS on the watch only goes on when not connected to the phone.

Stop watch from getting Location from Phone, without turning off Bluetooth

I've noticed that if my watch is connected to my phone via bluetooth, it will try to get location data from the phone rather than the watche's own GPS.
Under normal circumstances that's not a problem, however when I go hiking, I keep my phone in my backpack and it loses the GPS signal. That means the watch also loses location data and no longer properly tracks the hike (or any other activity where the phone might not have a GPS signal).
Is there a way to force the watch to use its own GPS even when bluetooth is on?
Turning off bluetooth on the watch fixes this of course, but then I no longer get notifications of text messages coming in while my phone is not easily accessible, which is kind of the point of the watch in the first place.
Maybe turning Off Location on phone ?
