You can register as an beta tester of google maps clicking some link in description of google maps in play store.

May be crashes and feedback have more influence then and if some of us take part the problem is fixed sooner.
[MTCD  Android Head Units Q&A] echudoba:
Yes, more users should do this. I did it a few weeks ago, tested the beta's, left feedback, and then went back to 9.46.2.
[MTCD  Android Head Units Q&A] f1x:
I analyzed a bit root cause of Google Maps hangs (it was really annoying for me). I observed a problem related to the procedure of testing the internet connection by the Google Maps. Each route calculation routine triggers Google Maps to download a small file in order to test the internet connection. Mentioned file is stored in the cache dir. Microntek developers did not consider how to ask app to quit in gently way but decided to make a force stop. In few cases it can break writing to the cache. I have made a workaround to clear the cache every time when HU is going to be 'operational' (after boot up or wake up). After 5 days of tests I did not observe any hangs or crashes with the latest version of Google Maps.

In attachment I put app which clears the cache of Google Maps. App requires root access. You can add it to the autorun using MtcdTools or any other app which manages autorun of the HU. Please test it and provide your feedback or donation :).
[MTCD  Android Head Units Q&A] iwl:
If that's the case how can this bug be reported?

The shutdown looks to fast in my opinion too, compared to other android devices.

Would add to other bad quality implementation, high current draw in sleep, no low voltage shutoff but boot loop, ...
[MTCD  Android Head Units Q&A] iwl:
After manually calling this app and rebooting several times, newest maps beta hasn't hang on several navigation tests to far locations, hanging for sure one or other try before.

But now it crashed again, think have closed the app in between.

Another problem I've just recognized is when maps is gone background by pressing home button "OK Google" Input is still sent to maps and not to google app, looking different and different results.
[MTCD  Android Head Units Q&A] xdamember2:
Just got a px3 7.1.2 and Maps is fine so far. It is significantly slower than the px5 for installing apps.
[MTCD  Android Head Units Q&A] marchnz:
As an upgrade or new unit? Did you enable sleep?
[MTCD  Android Head Units Q&A] xdamember2:
New unit. I left it at the default I think they call it "auto sleep" and it draws 8 ma. Slow install problem is resolved after restart.
[MTCD  Android Head Units Q&A] echudoba:
Unfortunately did not work on my hu. Tried clean install of 9.63.1 maps. restarted and clean cache and maps memory, still no luck. Worked a few times but keeps hanging on starting of navigation and start driving. Start driving is the easiest test to prove fix. Attached a long log cat file for your info. The last two hangs were at 17:43 and 17:49. Have your fix starting with screen active and ran manually during tests.

At the moment, the only solution ist version 9.46.2.

[MTCD  Android Head Units Q&A] marchnz:
Fix for Google Map hang/crash

Fix for those who have missed the fix posted elsewhere:

1. Root

2. Install Xposed

3. Install [Graser's Dasaita Tool] - click here to open thread

4. In [Graser Dasaita Xposed Module] add [Google Maps] to sleep whitelist

"White-List. *** XPOSED REQUIRED***

Application to modify the behavior of MTCManager.apk, which is the responsible of managing the sleep (standby) state of the headunit. This module allows to include in a list (white-list) all the installed applications you want to prevent them to be killed during the standby."

Enjoy Maps no-longer crashing after sleep.
[MTCD  Android Head Units Q&A] iwl:
I experienced the trouble with maps from first time use on.

Do you really think that kill on standby matters?
[MTCD  Android Head Units Q&A] echudoba:
I feel the same way and the f1x fix did not work for me either. If anyone tries it let us know the outcome. I will give it a try eventually after I make sure putting maps in the white list does not draw more standby current (8.5ma now). FYI Tasker in the white list does not add current draw and works starts properly.

Why does maps 9.46.2 work so good, what did google change?
[MTCD  Android Head Units Q&A] makes2068@gmail.com:
Another update to dasaita stock ROM 20171023, maps not working.

So went back to version above, again ;-(

It is hard for me to understand,too what the differences are between the working 9.46.2 version and an actual one...
[MTCD  Android Head Units Q&A] marchnz:
The work around (graser tool/Xposed to whitelist sleep apps) worked OK for me after testing multiple solutions. Frustrating that a proper bug fix is not yet available.

8mA is

infinitesimal

. For comparsion, an LED comsumes up to approx 20mA.

For example, to discharge a typical 60Ah car battery 50% with a drain of 0.08A (80mA, ten times the MTCD sleep load)is approx 1112.3 hours or 46 days!
[MTCD  Android Head Units Q&A] iwl:
Never forget the Rom is the problem Maps works on other devices
[MTCD  Android Head Units Q&A] xdamember2:
None of these solutions worked for me. I did have a 2GB PX5 working with the latest Google Maps, until I tried to update a couple of apps while driving. The navigation screen went black and I never got it working again. I attribute this to running out of RAM. Google Maps works on the PX3 Nougat but that's just a 32-bit processor so I sent it back. The Joying works ok with the latest Maps version, but it predictably crashes after 2 hours, maybe because of memory. Now I have a 4GB PX5 but have not been able to get the latest Maps working stably. I'm back on 9.42..3 and I'm not yet sure if it's ok, I have to restrain myself from updating Maps. Of course this is temporary, one day there will be an MTCD Oreo.:(
[MTCD  Android Head Units Q&A] iwl:
Are there PX5 with 4GB Ram?
[MTCD  Android Head Units Q&A] marchnz:
You didn't get Xposed and whitelisting running correctly. This is a viable working workaround. Complain all you like I doubt Oreo will bring anything other than the same bugs. Isn't the OS that is the problem, it is the MTC service and app layer.

The whitelist makes sense; it becomes more like a normal phone.
[MTCD  Android Head Units Q&A] iwl:
I don't understand becomes like a normal phone by Whitelist?
[MTCD  Android Head Units Q&A] echudoba:
In my case tried and did not work either like xdamember2. My hu will crash on navigation the first time I run it from a boot. I completely uninstalled maps. Did a fresh install of latest version, crashed on fist navigation or start driving. Hu never had a chance to sleep. Also tried with whitelist, which I use for other apps so I know it works. Possible different hu act differently depending on apps installed. As far as a possible memory issue you can see how much memory is use in apps. Mine never uses more than 1.3g in max memory used. Hope the real issue is found and corrected in a ROM update.

Well known problem where GMAPS is forceably closed on unit sleep.

Solution is root, xposed and Graser whitlisting xposed module to prevent MTC forcing gmaps closed.

I have a second unit and it too has had xposed/Graser Whitelisting GMAPS solving the problem of crash after starting navigation from search.

Anyone with this problem, suggest using this workaround. A workaround is better than a crash/hang. I doubt the bug will be solved anytime soon as support for MTC is non-existant.

---------- Post added at 01:10 PM ---------- Previous post was at 01:09 PM ----------

Uninstall Malaysk and install factory. I have no doubt - I have a second unit now with a working solution of root/xposed/Graser whitelist module.

[MTCD  Android Head Units Q&A] Danno1975:
So unless you really want to start tinkering with root and stuff (beyond me as a general user) the current google maps (and I also found gmail and browser) will just randomly fail?, whereas non google apps such as IGO and Waze work just fine?. Seems ironic.

What’s causing and android OS to mess up the three core google apps it has???.

How does the sleep/shut down affect google maps when I’m generally it using it or other google apps?.

My issue is that when I do need Nav, and mail etc, sometimes it works well, other times it opens and stops, something new it just hangs and rarely it will open and instantly close on its own repeatedly and even a reset/boot won’t help.

Next time out it’s fine.

And when it hangs it always seems to crash as you approach a complicated roundabout.

Not a programmer so how is the shut down affecting the app when driving (in laymen’s terms) if possible :)

Also someone noted a roll back to an older version for maps maybhelp?, does this work for gmail and google browser too and where can I get the older versions from?.

Finally I know what the MCU is and the ROM, I assumed the issue Is the rom but now someone be is saying it’s the MTU!?, what’s the MTU?.

Got totally F’d over in traffic by Waze today and can’t seem to fit nd our how to get the in built igo traffic to work so really really would like google maps to work reliably on my Px5.

Cheers.
[MTCD  Android Head Units Q&A] iwl:
A: If that forcing closing is a problem why doesn't xposed just properly shutdown every app?

How about telling Malaysk to just set it up that way?

B: Malaysk use the last hotaudio kernel, this is just the factory kernel, there is no other, or am I wrong? So what is the difference?
[MTCD  Android Head Units Q&A] xdamember2:
I hope I'm not speaking too soon but the current version of Google Maps has been working ok for me for over a day now. What made the difference was to set the DPI back to a higher value. I'm using 240 now which may be the original default. Since my unit is a 10" one of the first things I did was to reduce the DPI to 161. At 240 Google Maps seems OK. I'm also using two of the earlier suggestions in this thread, mapscachecleaner on cold boot and adding Maps to the whitelist. I've tested both taking long drives and letting the unit sleep for a period of time. Before this I was using 9.42.3 and I found it usually crashes eventually after navigating for more than 2 hours. It occurred to me to try resetting the DPI because Maps initially crashed during the first rendering of the map during navigation, suggesting it could be related to graphics. Sorry if this isn't helpful.
[MTCD  Android Head Units Q&A] BobbyZee1712:
It is helpful, tell us more after few days and more driving please
[MTCD  Android Head Units Q&A] xdamember2:
Today I added an intermediate navigation stop, but after resuming from the stop it did not initialize navigation to the ultimate destination. I re-entered the destination but Maps then crashed. It was back to normal after entering the destination a 3rd time. So it appears this is not a complete solution.:(
[MTCD  Android Head Units Q&A] montrelim:
Is there any solution for GMaps crash yet?
[MTCD  Android Head Units Q&A] BobbyZee1712:
read Thread and u would know - NO
[MTCD  Android Head Units Q&A] xdamember2:
I have learned g maps is less likely to crash if not using offline maps. I'm not sure which of the other remedies are necessary (white list, cache cleaner, som cooling). I have confirmed the correlation on 2 units, one with 2GB ram and the other 4GB. I haven't had any crashes in the car since deleting and disabling offline maps. I haven't tested for very long, but as soon as it started downloading it crashed and after download was unusable. After deleting it was fine again. It didn't help (with offline maps present) to use a giant fan or limit the cpu frequency. I'm using DPI set at 204, stock rom presently. Besides continued testing, I want to see the effect of storing the offline maps on an external sd card.:o
[MTCD  Android Head Units Q&A] homer.ali:
Hi everyone!

I would just like to add my 2 cents to this issue..

I've also tried to implement all of the fixes discussed in this thread including the whitelist app, the cache cleaner and using maps 9.4.6 but I was still getting hangs/crashes within about an hour of navigation.

I tried switching to Waze but unfortunately the same occurred after about an hour.

What seems to have fixed it for me so far is I took the top off of my unit, took the DVD player out and stuck a computer fan in it's place. Computer fans usually run directly off of 12V so I just wired it directly into my cars switched power.

The result for me was a perfect navigation experience after driving for 4 hours today.

Furthermore just having the cooler tablet seems to make it more responsive as it doesn't thermal throttle nearly as much.

I'm not saying this solution will work for everyone but I definitely think that it's part of the problem for at least some people-- especially those who are getting the slow downs on cold boots with brand new cleaned maps installed.

I hope this helps someone! Let me know if you would like some pictures and I'll take some!
[MTCD  Android Head Units Q&A] xdamember2:
Are you able to utilize offline maps? I concur that a fan helps aside from that.
[MTCD  Android Head Units Q&A] montrelim:
I would like to updated to that after testing as xdamember2 suggested, Gmap is stable and work as it should be after deleted offline map.
[MTCD  Android Head Units Q&A] homer.ali:
Can confirm offline maps works for me so far for a short drive (20 minutes today) with fan on and maps 9.4.2
[MTCD  Android Head Units Q&A] iwl:
But that's well known for long without a fan.
[MTCD  Android Head Units Q&A] homer.ali:
Yes sorry, I only meant to give my news as I had it.

Today I drove 2 hours from Sacramento to San Francisco using downloaded offline maps with the fan on and I experienced no crashes in maps itself..I did experience one system UI crash at a certain point when I tried to make a phone call using Google now voice but I was not able to reproduce this on the drive back (also 2 hours)

Just to reiterate, my setup is using maps 9.4.2 which is set to whitelist on the carsleep app by grasia and a computer fan sitting on top of the coreboard.
[MTCD  Android Head Units Q&A] iwl:
Isn't 9.4.2 the version working without anything, no whitelist also.

I only don't want others doing needles efforts.
[MTCD  Android Head Units Q&A] echudoba:
Yes 9.46.2 works with out any mods. Offline maps also. I have tried all the mods with the new versions and have had no luck. Just search for maps in "MTCD Discussion, Questions, Development" and read all about it in all the threads. The heat issue does not effect or slow down mine at all. I've done 9 hour trips with DVR and maps while streaming audio books on a iPhone. No issues using 9.46.2.
[MTCD  Android Head Units Q&A] makes2068@gmail.com:
Confirm this, only 9.46.2 is working. All other versions have issues. ;-(
[MTCD  Android Head Units Q&A] echudoba:
9.46.2 is what most users are using or landed on. Newer versions started having the starting navigation issue. Older versions seem OK, I have only tried a few myself.
[MTCD  Android Head Units Q&A] homer.ali:
Hmm interesting, for me I installed the fan after my 9.4.2 was freezing about an hour into any drive. I wonder if my issue was an isolated one in that case
[MTCD  Android Head Units Q&A] ZeligPC:
It this case the problem could be overheating (but I suppose all system should crash, not only Maps...), but newer versions of Maps are crashing also on startup, when the unit is still cold, so I don't think that's the issue.
[MTCD  Android Head Units Q&A] kaderekusen:
Has nobody else have the problem with the voice of google maps navigation? If i hear music very loud (max volume on unit)

The voice of google maps kick me in my face...

Wrong thread.

---------- Post added at 08:43 PM ---------- Previous post was at 08:42 PM ----------

Wrong thread, not related to Google maps hanging and definitely not progressing the resolve of the issue. Turn your head unit volume down and ask question in appropriate thread. If none exists suggest opening a new thread and not hijacking this.
[MTCD  Android Head Units Q&A] echudoba:
There are three places to work with volume levels, maps, I think driver settings (navigation checked), and system settings 126 (turn music up, system down??). I'm not in front of my head unit now so I can't give details. Look around and experiment in these. For further move to proper thread.
[MTCD  Android Head Units Q&A] xdamember2:
I tried the current version of G Maps again, with offline maps, and I found it helps to set the Animation Delay Scale (in Developer Settings) to .5. I have been using it today like this without any failures. Here are my other settings:

DPI 204

whitelist G Maps

SOM cooling fan with a delay relay so it stays on while the HU is shutting down

mapscachecleaner runs on cold boot

I don't know which of these settings are relevant / necessary, except the whitelist seems necessary. I will continue to test, this could just be more fool's gold.

Update: It appears it works ok if I don't install any offline areas.

Final update: It crashed again and I'm tired of bandaids. I've switched to an Allwinner T8. I see the Android 8.0 PX5 is now available but not in the 10" universal variety and I don't really want to buy some other style just for the SOM assuming that would even work.

Postcsript: The T8 loses GPS accuracy after sleep and finally Maps stopped updating position altogether after sleep. I am back to the px5 with Maps 9.42.3 including offline maps and doing ok for now.

Hi guys, I have downgraded maps to 9.4.2 with apkdowner and started google maps it is crashed and unis is restarted. Then I realize 9.63.1 installed automatically. My hu is also rooted. Do you know why newer version installed automatically or what else other options to downgrade ?

I got my Oreo PX5 yesterday and installed it this afternoon. The ubiquitous Maps crashes are not occurring. Admittedly I've had a few applications stop while configuring. This seems to have subsided and I had no failures while driving. I have downloaded an offline area of maximum size around my home location. All apps shipped with the unit were up to date as received. The only downside at this time may be the inability to root (I tried Kingoroot and Kingroot). MTCD Tools works for configuring autoruns. MTC Dialer works. To activate it from Google Assistant make a call from Google Voice Search and select it. Sorry if it looks like I'm hijacking the thread, but I didn't want to start a new one.:cool:
[MTCD  Android Head Units Q&A] warata:
I was relieved to hear that Googlemap will not crash because I also ordered oreoPX5 this morning.

The credit that you have confirmed that upgrading to oreo is one way to solve the problem is great.:good:
[MTCD  Android Head Units Q&A] xdamember2:
Unfortunately I had a "maps is not responding" this morning while driving. Still, this is not as bad as freezing repeatedly when starting to navigate. I've experienced the "not responding" occasionally on all versions of Maps on the PX5 (I think). I'll try to put up with this occasional issue. It's good to have the latest version of Maps running including offline maps.

[MTCD  Android Head Units Q&A] mum1989:
can you review and do benchmark of your PX5 oeo unit please ?

it's 4GB ram ?

thanks
[MTCD  Android Head Units Q&A] xdamember2:
Yes it is 4GB. Hardware appears to be the same as the 6.0 4GB units.

I will review it, but I am not experienced with XDA style reviews so this is going to be more of an Amazon style review.

The model I purchased is https://www.aliexpress.com/item/New...avi-With-PX5-Octa-Core-Radio/32846184632.html

Pros:

Oreo features

Google Maps does not freeze during startup

Fits nicely in a standard 2Din without protruding and required no physical modification

No audio stuttering

No audio glitches when switching apps

Cons:

Tasker -> Export app failed, unable to sign.

Not obvious how to root, I tried Kingroot and Kingoroot.

Developer options are enabled the standard 7-tap way, but I could not then find the settings. I tried to get at the settings via Tasker but that didn't work either.

Observations

Antutu score about 23,000. This is surprisingly low compared to the 6.0 PX5. It appears to be the big/little octacore style, 4 cores have a higher maximum frequency than the others. The cpu and gpu temperatures stayed below 80 during benchmarking. The temperatures are now readily accessible to apps.

A couple of times Google Maps got sluggish and then crashed. Since then I moved offline maps to the external sd card. This was ok for a day however I am not using the unit right now and it should be tested further.

This unit of course has deep sleep, but without root it isn't possible to make a white list. Google Maps remembers the destination and stops (if any) but it takes time for it to restart and get to a point where it can begin navigating. It won't do anything until the wifi connection is re-established. So the benefit of deep sleep is somewhat negated, at least in my use case.

The screen on this model is ok, but there are certain angles of sunlight that make it unreadable without shielding it with one's hand.

MP3 playing with a non-stock player (I didn't try stock) has the same issue as before, i.e. it doesn't resume where left off.

A couple of times the unit did a cold boot instead of coming out of deep sleep. I think this had to do with unusual situations like shutting it off while playing mp3.

Factory settings password: m123456

That's all I can think of. I can easily power it up on the bench if there are any questions,.
