Android Auto not using car GPS Antenna?

Hey Guys, i searched located a few threads but cant find a definite answer...
I got Ford Sync 3 with AA.
My car headunit have factory GPS software and antenna on the car.
Now i have updated my headunit to firmware with AA and CP.
When connecting AA everything works fine, but when i go to Google Maps it always require me to turn my phone GPS to High Accuracy (on) mode.
i was under the impression if my car have built in antenna it will utilize that...
Is it a case where for my car specifically (Ford 2016 Mustang) if built in NAVI is off then there is no power to the GPS antenna? or is it a setting i cant seem to find within AA?
thank you.

I am using a Pioneer headunit connected with the car's built-in GPS antenna, and I frequently use Android Auto. My experience is that AA used the phone's GPS antenna, not the one connected to the headunit (which should have better reception).
AA very probably uses the phone's antenna because the good people at Google expect some headunits to not have a GPS antenna connected (after all no GPS on your headunit is a major selling point for using AA), and they have no way to check that by software.

chinese android head unit problem Play Store and Bluetooth

hello everyone,
I just installed a SEICANE chinese android head unit in my Fiat Ducato from 2017.
I connected the ISO port directly to the 2 connectors from the car, I've first tried to use a power harness including the CanBus decoder, but then the HU is dead. Without harness , the HU works (I guess the car already has a CanBus built in?).
The radio works very well. Also Wifi works well, I can surf on the Internet. But some apps I can not download (using Play Store). For example when I try to download TomTom GO, the HU tells me that there is no Wifi (although there actually IS Wifi!). Other apps are no problem to download (I've "fixed" this problem by installing Sygic i.o. TomTom).
I paired my Samsung XCover3 via Bluetooth and also problems: when I try to make a phone call, sometimes it goes to handsfree (like it should), but sometimes it does not (although the phone display opens on the HU). I did the pairing 10 times , but no difference. I also tried to make an Internet connection using Hotspot or tethering, but that also does not work.
I resetted the HU, but no improvement.
Does somebody knows these problems (and has sollutions to it)?
Regards,
Peter

Wifi (randomly turning off) and SD card issues (randomly unmounting) PX5 MTCE unit

*** Edit ***
So I realized that not only SD and WiFi are affected but also USB ports as well. Meaning that DAB+ Radio also restarts from time to time...
Maybe a hardware issue?
****
Hi there,
just bought a MTCE PX5 unit with Android 8.0 (4 GB Ram, 32 GB Rom).
MCU version is 2.94_1 MX2
I have two severe issues I can't get rid off:
1.) Wifi is turning itself off randomly every some minutes. I have to reactive manually which is working. But very annoying when navigating or listening to web radio.
I already tried wipe data, installed different Oreo roms, changed location accuracy to "device only" - didn't help.
2.) My SD card (I tried 3 different with different sizes and classes) are getting unmounted every some minutes and remounted immediately.
Also I didn't find a fix for this yet.
Any Idea what I could try to fix both issues?
Best regards,
thanks a lot!
Christian

Got the same problem here with the wifi at first. But now I can't turn it on and it's Mac address shows 02:00:00:00:00:00

Mine wifi has gone too and same issue, Mac address showing same thing. Anyone had any luck @[email protected] @GFourms

I have exactly the same problem with wifi. I tried to install hal9k oreo rom, but still not working. My mcu version is MTCE_GS_V2.90c_3. I'm using a huawei e8372 modem, when I connect this to usb the network range icon show up, but there 8s no internet... So I use wifi but still turning off and i must to reactive this again

HELP! Dasaita PX6 Max6 Headunit wont connect with iPhone Hotspot

I’ve purchased a Dasaita PX6 headunit. It’s advertised as Max6. Here are the specs:
Build number:
rk3399-userdebug 9 PQ2A. 190305.002 20190828.185647 test-keys
Kernel version:
4.4.167
#593 Tue Aug 27....
MCU Versipn
MTCE_HA_V3.30_2
I am also running an iPhone XS on iOS 13.2.
I’ve tested the hotspot on my iPhone with other decided and they are able to connect. I’ve also tested other iPhones on the Dasaita to see if it will connect to them. Unfortunately, I’m not able to get any iPhone to connect to the head unit. The head unit is able to connect to other SSID that are not iPhones. Can anyone help me with this? Thanks!

Have you seen this?

Yes, I have. I've tried all the tips. Nothing. It's weird because the head unit can pick up other hotspots/wifi SSID, but it does not find my iPhone. Initially, I could see the iPhone hotspot. It says "Connected...Saved" - this repeats 3 times and then it goes away.

Is your hotspot configured for G and N?

Not sure - whatever the standard is for iPhone XS running iOS 13.1.2 - I assume it's AC...

There is no way I can configure this - it happens automatically in the background, configured by Apple.

Even with the new MCU 3.37 update, I still get this problem occassionally. I've been turning the personal hotpot on and off multiple times, before the wifi connects itself!

Dude! You’re luckier than I am! I have that MCU as well, but my hotspot is not found ever! After it’s found the first time, it connects, saves the SSID, and then never displays or connects ever again.
I think this is both an iPhone AND head unit issue. It’s weird because not only can I not see the iPhone hotspot on head unit while sitting in the car, but I can’t see it on other devices either. However, as soon as I walk about 5 feet away, I can see the ssid.
So weird.

Hmm, when you turn on personal hotspot for your iPhone, you got to make sure to keep the screen on, at the page where to turn on your hotspot to wait for the headunit to connect. Then keep trying multiple times, or change your hotspot password!

Could be the location of the WiFi antenna.

I had the same issue on my Samsung Note 10+, I had to turn off "Allow 5ghz" in my wireless sharing options advanced settings. Then my MAX6
connected.

I was having a similar issue with my iphone hotspot being found, but not connecting, just saying "saved." The was being caused by the bluetooth connection between the head unit (car kit) and the iphone. You need to go into the iphone's bluetooth connection settings for the head unit (car kit) by tapping the "i" icon and then turn off carplay in the settings there. This should allow the iphone hot spot to be found and connected to by the head unit. It worked for me.

Same for me... Sometimes, turning off and on the iPhone then connects. in some cases it connects immediately ... boh

Unstable Bluetooth Connection issue PX5 MTCD/MTCE Android 9

Hey guys.
I'm on a Xtrons TE103AP which is basically a PX5 MTCD/MTCE unit. I was previously on stock Android 8.0, had no issues with OBD Bluetooth pairing and running ECU based programs off of it. Moved to Malaysk's 8.0, no issues as well. MCU back then was the MTCD the unit came with, GS 2.71 if i remember correctly
I took the plunge and moved to Android 9, first with Hal9k's v4.0, then Stock Android 9 for GS units (the most recent release). I tried these 2 combinations with different MCU's from GS 3.00 right up to GS 3.44 (latest). While i'm able to pair with my BT OBD2 Adapter with no issues, i'm unable to maintain a connection. The bluetooth OBD icon on the task bar connects and randomly disconnects causing programs (torque and hybrid asst etc) to drop connections with the ECU.
The behavior is constant. I've tried changing selecting different bt drivers from the factory menu, to no avail.
Anyone can shed some insight?
Thanks!

What BT type? Is it still OK on Android 8?

Thanks for replying!
It was on WQ_BC6 by default. That was on android 8 (stock) and on Malaysk. I tried reflashing back to Android 8, but on the new MTCE MCU's. Problem persists.
Could it be the MCU causing issues? I've tried almost all the GS MTCE MCU's and they all produce the same issue.
Other Bluetooth functions work fine. A2DP and phone sync is perfect.

How have you tested your OBD adapter to confirm ithe adapter isn't the issue? Is it a genuine OBD adapter or knockoff?

Already tested. Its a rebadged ELM from Xtrons. They charged a premium for it, moreover it works fine on my android tablet. No connection drops or the sort. The exact same OBD was working fine with Android 8 as well prior.
A new update. I just realized that while i'm able to pair my phone and stream A2DP, and sync contacts with my phone, incoming calls route no audio or voice. Incoming calls trigger a prompt and i'm able to answer, but there's no sound or pickup from the microphone. weird....
I've tried selecting BC8 and BC6 in the factory settings... not quite sure what i'm dealing with. I'm on GS3.30bd, the BD modded MCU. Will see if an unmodded MCU fixes the voice issue.

@marchnz I flashed an unmodded GS 3.44 MCU and bluetooth audio worked properly. the OBD connection was still intermittently dropping. I then moved back a step to GS 3.40bd (soundpatched) and had no issues as well with bluetooth audio. I suppose the bluetooth issue was from the modded 3.30 MCU.
The Bluetooth OBD connection drop still hasn't been resolved however.
Any suggestions?
