Help! Google Maps re-routing non-stop. - MTCD Android Head Units Q&A

I have just purchased and installed an Android 9.0 Navigation / DVD head unit for my 2010 Toyota Camry. The system is very snappy and came pre-loaded with many useful programs; one of which is the iGO navigation app. Another app on there I was glad to have is Google Maps. After the completion of the installation, I road tested the navigation software and found out the iGO navigation app worked very well. I then tried the pre-installed Google Maps to navigate; it was able to track the GPS receiver to pinpoint my location right away; however, Google Maps attempts to re-route continuously (like every 5 seconds or so) as I drive towards the destination. I'm not able to stop it from doing this; it's so frustrating and is unusable as a navigator.
Does any forum member have a clue to what is happening to my head unit? I thought I might've been able to get away with just using the Google offline maps, but I suppose an active mobile data connection is required? Thank you.

No GPS Fix - Unless using ATT Nav.

So I know a lot of us (probably you if you're reading) have had tons of problems with the GPS regardless of ROM vesrsion. I've tried several ROMS (currently using Romeros (great)) and several radios (currently .28).
And here's what I've found. GPS will almost never work - except if ATT Nav is running. Then it works every time. However, as we all know, once you log into the Nav - you're being charged. This brings me to my quesiton. Have any of you Moderators / Hackers tried seeing what's in the ATT Nav that's enabling the GPS. I spoke to HTC today and they told me that the phone was designed NOT to work unless ATT Nav is running in the background. So what's that program doing to activate the GPS. And (and I'm not sure if this is how it works) couldn't we just install the app, and take a picture of the used dll's and registry changes to see what it's actually doing - and write a small program to do the same thing?
Thanks,
BZ
My GPS works without even having ATT Nav installed. It just takes awhile to 'warm up'. When I'm planning to use the GPS I will just fire up my map program, iGo or Google Maps and wait. It takes about 2 minutes to start working and then I get good GPS signal until I'm done.
i dont think this is true, since people with the unlocked/unbranded touch pro are having the same gps issues.

Same here. I go out to start the car and the nav program (CoPiolot or google maps) and come back in a couple minutes. THe GPSTest app doesn't seem to get it started any sooner, just tells you what sats it's seeing and the signal strength of each.

There is a whole thread on this subject with a cab file called GPS Tweaks.cab in it. Installing that CAB file fixed all my GPS issues .. Google, Windows Live Search, iNav all make proper use of the GPS now.
My gps works with google maps..
Launch quickgps, run google maps, it picks up sats in 1-3 mins.
ATT Fuze, stock rom, google maps
having gone through Advanced Configs and changed a few settings on the GPS, my GPS seems to be working perfectly within reason of a GPS on a phone. As long as i am outside or by the window, i get at least 4 sats in no more than 1 minute. most of the times, it is accurate to at least 20 feet if i am not in fast motion (car speed)
No problems here. Stock ROM, never installed AT&T Nav, takes about a minute or so to warm up, and loads Google Maps and Liver Search quickly. Very accurate - right down to standing under a tree in a park.
There's nothing to what you are saying - it must be a coincidence. It's been proven that the GPS is not locked to AT&T Navigator.

Tomtom navigator GPS Fix problem

I have an inconsistent and strange problem with my gps fix. Especially with a cold start. Sometimes Tomtom Navigator gets a fix within +/- 2-5 minutes. Sometimes not after 20 minutes.
Strange thing: Google maps is always able to get a fix, even if TomTom is not able. Once Google Maps gets a fix, I can start TomTom and then he finds a fix too. So sometimes in order to get a gps fix with TomTom, I have to start Google Maps.
This is a problem, because Google Maps uses internet, which I don't want if I am in a foreign country(Belgium for instance).
I am running Energy.RAPHAEL.21901 With Coockie Home tab 1.7.1,
Navigator 7.915(9196)
Radio version: 1.10.OliNex(don't know if it matters)???
Just ask if you need more information. Hope someone can help me!

[Q] Problem With Nexus S GPS

Hi All, Please assist me, my new Nexus S is not connecting with the navigation system. It will search and search and them turn off. The funny thing is that the map worked perfectly, its just the navigation. Thanks,
Iwodamiorie
This is a known issue with new Nexus S's. It's caused by the Maps program giving up on the GPS too quickly. The solution is easy: download a 3rd party GPS utility app (I use "GPS Test"). Allow that app to run until it gets a solid GPS fix, and after that the Maps app (and by extension the Navigation app) should work correctly.
Note that getting an initial GPS fix could take up to several minutes, so be patient. The good thing about GPS Test is that it shows you the satellites as it sees them, so you get an idea of the progress.

Looking for a true offline GPS alternative.

There are some places I will be traveling to that I won't have signal. Google seems to currently support map caching of 10 miles. That doesn't help me much at all with how long some of these drives are going to be.
So I'm on the hunt for a true offline GPS solution for my Android phone. I read some reports from early June of this year that Google Nav was getting "true" offline navigational options this summer, but I haven't seen it yet, unless they were playing off the 10 mile map cache feature to be their "true offline" feature (which is just a bad joke if that's true).
So my questions are basically this. Does Google Navigation have TRUE offline navigation yet? Or is that still a work in progress?
If Google Nav is out, what alternatives would you recommend? I want to be able to download the maps and utilize the app against the maps without the need to ever touch wifi or mobile internet (with the exception of initially downloading the maps, of course).
Any suggestions?
Ndrive all the way. I use it since long time and never let me down.
I'll second that works a charm.
iGo user here. also, you can have Google Maps cache multiple areas
Google cache isn't what I want. It seems you can only cache 10 mile blurbs. There are some areas I might be without signal for significantly longer than that.
I'm still trying to find out if Google's offline thing is coming yet or if their cache option is just that. I sure hope not... as it's not a true "offline" GPS solution whatsoever.
Any further suggestions?

GPS doesn't work in Google Maps - but is okay in Navigation

I've got a problem. When I open Google Maps it doesn't seem to activate my GPS so my location is decided by the operator-network and/or wifi, and is not very precise. I've tried to keep Google Maps open for a long time but my location is never that precise as when the GPS is activated. Also if I log into Android Device Manager on the web, I only get a location with an accuracy of 1.5-2 kilometres so that's neither located by GPS.
But if I then enter a route in Google Maps and use the Navigation, the GPS is turned on and everything is fine. It's the same if I use Sygic GPS Navigation. I've got Avast Anti-Theft installed on my phone and if I log into avast.com and send a location command to my phone, it's also located by GPS with an accuracy of 5 metres.
I've installed 'GPS Status & Toolbox' and set the app to show an icon in my navigation bar when the GPS is used. And it's the same as described above - when Google Maps is open there's no icon but when I use Navigation the icon it's there.
I'm pretty sure that on my last phone (Samsung Galaxy S II) with Android 4.4.2 Google Maps also used the GPS and I've got a precise location every time, so my question is how to get it in the same way on my new phone (Sony Xperia Z1) with Android 4.4.4? There are many times I just want to see on Google Maps exactly where I am without using the Navigation directions to a specific location.

I'm having a similar problem to this where GPS is a bit inaccurate. Would love to hear peoples solves for this. Thanks.

Have either of you guys tried clearing app data and see if that works? Every once in a while I get that to resolve my issues.

i don't know about the gps not turning on at all, but it is a somewhat known bug on googles end when wifi is used to help location services, it frequently causes accuracy issues.
try turning off your wifi and see how it acts.
Yeah, off wifi it's more accurate. But yes, rooter, just cleared my app data and that did the trick, thanks.
