Does Android Auto cache data for Google Maps? - Android Auto General

So I'm planning to take a trip up north to Yosemite soon and T-Mobile doesn't have coverage in that area so I'll have to download an offline GPS app prior to the trip.
I tried using AA with the data turned off on my GS5 and Google Maps on AA was still able to track my location and I was able to lookup addresses I've already been to in the past. So now I'm wondering if AA is using the cached data from the vehicle or from my GS5. Would anybody be able to shed some light on this?

Yes, it is using what is on your phone. Whatever data you have available to you offline on your phone will be available to you offline on Android Auto.

Save the map area to be certain you have it ready for your trip

Is it still the case when you save the map area, that Live traffic is not available on the map?

You need an active data connection to receive live traffic. If you offline download a map area but still have an active data connection you will receive live traffic on top of the offline map.

Google Maps

hey guys, i am using the stock google maps on the phone. I take it that the "gps" it is using is free of charge because it is not using my data connection, what does use data is to load the map. Everything works well untill I enter a part of the map not loaded. Is it possible to have the map preloaded so that it doesn't need internet to view it?

No google maps works off of data, gps is independent- like you said.
GPS works like this (simplified): The satellites are all constantly broadcasting their ID number and the current time (from very precise clocks onboard). The receiver picks up the signals from several satellites. Because the different signals all had to travel different distances from satellite to receiver, the times in the signals are slightly different. From this difference, and from knowledge of the exact orbits of each satellite, the receiver can figure out its own position.
No data transfer needed, and also, btw, nothing transmitted from your phone.

GPS question

Hey guys quick question would the GPS still work on the n1 if you use it with only wifi. I was thinking of getting an offline map program and then using the GPS on the already downloaded map.

I heard that google will provide an offline navigation soon. Very soon.
So you don't have to go looking for anything.
GPS can work without any data at all, WiFi or cellular. It'll just take much more time to lock on the position.
Assistance data can be downloaded on WiFi as well as cellular data.

GPS = Provides a location. Besides speeding up an initial fix over data (AGPS) to get ephemeris data it doesn't care about data. And if you don't have any data available, it will download the ephemeris data itself after a few minutes anyway over the sat link.
What YOU mean is navigation... Google Maps? Waze? Those do require data. New Google Maps 5 coming out will not in certain circumstances, and there are other offline mapping programs out there, but most rely on data to download maps, routes, and create routes.

[Q] using GPS without data

I live in the US and am traveling in Canada. I switched off all data, but still have access to wifi. Can I use GPS without incurring data charges? I have Sprint and data charges are ridiculous. Texting is free, and I have the international calling plan so calls are 20¢ min instead of 60¢ min.
You can cache map areas in google maps. Cache what you need via wifi. I would then turn airplane mode, then turn your GPS on and you should be good.

Try mapdroyd app. U can download all kinds of maps of the worlds streets and turn data off.
I hope that helps
Good luck

Thanks! I think looking up my destination via wifi then turning on GPS will work. No data is on,GPS is spotty, but still works. Worked from Vancouver to whistler.

[Q] pls answer. tq

Hi, I Live in malaysia. Was wondering is there any GPS Navigation app in the market that doesnt requires a mobile internet or WIFI while on the road? Thanks
Sygic aura, that having malasia coverage
Others are navigon, ndrive but i dont know these having malasiya coverage
Dude or dudette..get your data plan..no meaning having such smartphone without the data plan ;P

Im Using a unlocked one. dont rely on data plans that much
ya, sygic aura wont need data plan once you install n download map.
and as per my experience Sygic is best among other i have used e.g. MapMyindia, Ndrive, Navigon
use wifi to cache over all the data in google maps and then u can use it offline

Though it requires active data connection. Try it by data off n wifi off, it will say 'data connection lost'
It just helping to reduce data consumption

[Q] Bluetooth GPS and Galaxy Tab 2 7"

Hi Everyone.
Does anyone tried to use external bluetooth GPS reciever with Galxy Tab 2 7" (P3110) with Bluetooth GPS App from Android market?
Also, do I need root for this app to run?
Marek.
Why use an external GPS when it has GPS built in?
As far as I know it has A-GPS.
Or maybe I'm wrong...

A-GPS is better than GPS. It means GPS plus the ability to lock on quicker using Wifi and cell tower positioning.

"Reliability: Location determined via A-GPS are slightly less accurate than GPS GPS devices can determine location coordinates to within 1 meter accuracy
Cost: It costs money to use A-GPS devices on an ongoing basis because they use mobile network resources. GPS devices communicate directly with satellites for free. There is no cost of operation once the device is paid for."
Checkout last 2 points about Reliability and Costs. As a wifi-only p3113 user, having the ability to connect to GPS sat (even with no internet) would be a HUGE plus. So I would love to know how this bluetooth workaround works!

Have you tried? With wifi off I lock on to GPS in 2 seconds. Offline maps navigation works perfect... what more do you want?

Oh and from Wikipedia...
Assisted GPS, generally abbreviated as A-GPS or aGPS, is a system which can, under certain conditions, improve the startup performance, or time-to-first-fix (TTFF) of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers.

Well, instead of buying a GPS, I added some money and got a 7inch tablet P3113 also.
I have no tried offline GPS yet, how accurate is it? does re-direction work? which app would you recommend?
thank you

Accurate enough? Yes redirection works. Google maps has an offline feature. Or you could try navfree.

I love it when people are always confused about A-GPS.
A-GPS is BETTER than just GPS.
Assisted GPS means, that instead of just relying on the GPS satllites, it helps setting the position from WIFI and cell network.
It does NOT cost any money.
It is also handy, when you are indoors, so your device does not get a position fix from GPS satellites.
Besides, this samsung receives the Russian GLONASS satellites in addition to the American GPS, so its very precise.
My 10.1 tab2 (has the same receiver) sees 15+ satellites indoors!
GPS test shows precision down to 1m.

A-GPS need data connection
Hi, these posts are great to explain the difference between the A-GPS and regular GPS, but what happens if you do not have a data plan on your tablet and you are not in a wireless range. There is no way to activate the GPS.
The only way I have been able to use my no data Samsung 10.1 is to activate the GPS while in a wireless area then I can go for a drive (will always stay connected). If I would try to activiate the GPS on the road, I am out of luck.
Any work arounds?
Tether your phone to it....or. ... dont use a tablet for directions use your smart phone....and if you tell, e you dont have one then go return your tablet and get a real phone...

GPS works fine away from wifi on my tab-2 7 inch. It has real gps and doesn't need a wifi connection. You do have to turn it on in system seyyings though,

what did you do to get it to work without wifi? I have all three boxes checked in settings under location.

I have a Tab-2 7 inch with no G-whatever. The GPS is real and doesn't need anything other than to turn it on. It works fine. Try "GPS Test" it will tell you what is going on.
Just a point, an external GPS module will have about 1/2 the positional error of the built in GPS if you have WAAS or equivalent DGPS coverage. I get about 30 feet peak to peak error with the built in GPS and about 15 feet with my external Qstarz unit.
Tethering
Tethering your phone for GPS use will eat up your data plan. T-Mobile for example will limit your roaming data bucket if your phone is not within their network. The GPS feature of tablets is nice and the maps are large but I use a separate GPS unit for long distance driving and there's no extra charges. I bought a unit from Costco with free map updates for life! I would rather tether my tablet for internet use while on the road, it breaks the boredom with your passengers and they can watch Netflix too, depending on the signal. I do find that there is a lag connecting to the internet because the signal has to refresh with new tower signals.
Do you have to have a WiFi signal to use the Gaps? I lobe using my tablet in my truck but don't always want to connect my tablet to my phone

Assuming you mean A-GPS, no, the A- bit (assisted) needs data but that's just to speed up the initial fix time.
However, if you want to do something useful with the information about where you are, you may need a data connection; Google maps for example needs a data connection to get the maps, unless you have pre-cached them for the area you are in.
