Apparently Android Auto can either use the GPS in the connected head unit or the GPS in the mobile device itself. As I understand, Android Auto will always prefer to use the GPS in the connected head unit. (which makes sense: typically has better antenna reception, doesn't drain the mobile unit's battery, etc). How can I tell which one is being used ? When the phone is in the car, I put it in "The Grotto" below the climate control and connect it via USB. I call it "The Grotto" because it is really deep and I'm thinking there's no way a GPS can reach in there. Yet my Android Auto works fine and never loses GPS signal. So something else must be going on.

I have a Samsung galaxy tab 2 p3100. I have an android application which uses its internal GPS to get Latitude, Longitude values. But the lat, long values getting from this tab is not accurate. So I want to connect an external GPS Dongle / receiver to tab and get lat, long values from the external device instead of from tab. I want to know is there any external GPS Dongle / receiver device that supports Galaxy tab2 or any other android device? And if yes, which is the device and how to connect it?

I use Android Auto a lot. My car's entertainment unit, which I connect my phone to via USB in order to use Android Auto, has it's own GPS antenna. But it's slow to obtain my location, and often downright wrong, like several kilometers/miles off. My phone's GPS is a lot faster and gets much better results. But it seems the external GPS in my car always takes over when I connect to it. Is there a way to disable it completely, and only rely on the phone's own GPS?

I have an android phone (Device A), and an android tablet (Device B). Device B has a decent GPS, but Device A's is pretty much unusable. I would like to use Device A for navigation, but to do so I need a GPS quality only Device B has. Is it possible to make Device A accept Device B's location as an external GPS signal (i.e. with the usage of mock location) while none of them being rooted? If not, does rooting Device A help? *I am interested in a general answer, but also in a more device-specific one if it is better: Device A: Prestigio 5517; Android 4.4 Device B: Samsung Galaxy Tab 8.4 WiFi; Android 5.0*

I have 5 mobile devices with me, all these devices have GPS. On my map i need to view all the devices wherever it is located. And GPS will be turned on. Please help me

I've been looking at a very inexpensive bluetooth GPS (DeLorme Earthmate BT-20 ) to pair with my Archos 43 Internet Tablet running Android 2.2. Is anyone aware of a compatibility list that I should be referencing when considering pairing my device with a bluetooth GPS? I assume that the Android app will be used to reference maps, and the GPS will simply provide coordinates, but I may be mistaken.

Having read excellent answers about using external USB devices on SmartPhones (HTC Desire in my case), I would like to complicate the issue still further: I'd like to use a Windows emulator on the Android OS in order to run an external AIS dongle (and possibly an external GPS). The reason for this is that suppliers of these maritime safety devices seem to make them only with drivers for Windows (occasionally for Apple OSs too), but not for Android/Linux. The point of what I'm trying to do is to avoid using a laptop at sea A)as they are vulnerable and have to be kept inside, B) go wrong at sea anyway C)have long startup times D) most important of all, they use a lot of battery power so can't be left on permanently. What 'every' boat owner wants is a portable device that can run C-MAPS (sea charts) on a program called OPEN CPN (freeware) without entering into the equipment race by various 'big screen' GPS manufacturers who sell their various charts in various formats at exhorbitant prices. So I know I speak for *at least* tens of thousands of people who would love to find a solution to this issue. So does anyone know if/how to install drivers on, say, an HTC Desire to make it work with an external AIS dongle? (The data stream should be relatively simple if I understand rightly. Would I need Android drivers for the external USB or Windows drivers for it (if a Windows emulator is to be installed), or both? or is there a smart person who can make a driver for such external devices on a smartphone with Android and make himself 'millions' and avoid Windows altogether, (using perhaps Ubuntu or a stripped down Linux version (- OpenCPN works with Linux)). (Saying that, there will always be companies who make products with drivers for Windows only, so maybe via windows isn't the worst way?). Boats work on 12v so the optimal solution would be to find a phone/tablet as the 'mother part' in such a system that works on 12v - or - if a voltage converter is to be used, the more efficient it is, the better. The reason for wanting the device on all the time is for safety at sea - watching for an AIS signal 24 hours a day = a vessel approaching, or so that the 'anchor watch' can be used (= if the vessel moves more than a few metres whilst one is asleep, or the water depth changes, an alarm sounds). Having researched the issue, it seems no in the whole world has made a system that runs Open CPN that is not laptop based. I haven't even found a tablet based version capable of running the external AIS receiver/GPS as well, which I find almost shocking. But using a phone would mean far less power usage and a cheaper platform, available to all. The ability to then connect an external screen (by the helmsman, for out in the weather, daytime, let's say) would be the creme de la creme. Got all that? Good! ;)

I have an HTC One X which I like and carry everywhere, but the GPS is atrocious. It takes tens of minutes to get a position, loses it easily and it's not even very accurate when it has a signal. However, I also have a Garmin GPS which is fantastic at gaining and holding a steady and accurate GPS location. I'd like to use the Garmin as an external GPS in combination with android's mock-location feature, in my car. It is definitely possible to drive gpsd on a pc with the garmin - but I don't know how to use that to provide location data to android. The phone is already rooted and I'm not averse to hacking it a bit more, but of course simpler solutions are preferred. Initially I would be happy plugging the Garmin and HTC into a laptop but I'll move to a Raspberry Pi as soon as I know it works. Not really bothered about using USB OTG to connect as this is for in-car use. So: Can I use gpsd running on a PC to control a mock-location on Android? If so, how?

I know there's a number of solutions that allow you to use a Bluetooth-enabled external GPS antenna but what if you don't have Bluetooth? Does anyone know of a way to connect a USB GPS antenna to an Android device? **A little background: I just ordered this cheap resistive screen tablet primarily to be a less expensive dedicated Kindle/Nook Reader but I'm also thinking up other ways I can use this thing. One way I was thinking was as GPS unit mounted on my dash, only problem... no GPS.*

I have a few questions about Sat Nav applications running on Android. 1. Does the pre-installed sat nav app require a connection to the web? Does it operate in car and pedestrian modes and be updated automatically. 2. Am I right in thinking that the *after market purchase* of the Tom-Tom app can function without internet connection? Thanks for any replies.

As noted Asus is offering a GPS Extension Kit for the Asus Tranformer Prime TF201 . Does the module has a pass thru USB multipin connector to allow charging from the USB cable or does one have to remove the module to charge the tablet?
