[MTCD Android Head Units General] timo-n:
Hi Guys, i also have a Xtrons PX5 and did some Updates and had a few Problems. Some are gone and some are still present so here is my experience.

First of all i also have the Echo Problem. And iam Sure it is a Software Problem. The echo Comes after about 1-2 minutes still i have a active call.

If i Switch during a call to my phone and back to the head unit the echo is gone again for about 1 or 2 minutes so it cant be a Problem with the mic.

I have an external kewnwood mic with 2,5 jack mono.

Xtrons Support and the xtrons Forum "sofia" had no solution and it sucks because it is the main function i want to use...

Second Problem was the ODB Bluetooth Dongle. I bought the xtrons Bluetooth dongle and had an older one from my parrot Asteroid. But Pairing wasnt possible. Till Now... i find out that the Pairing only wasnt possbile if i tried to pair by the Standard Android Bluetooth menu at the head unit. So i went to the phone menu on the head unit and searched for new devices and pushed the pair button and it works without Problems. I dont know why but the Pairing in the head Units phone menu works without Problems. Also the deleting of older founded devices works here meanwhile the Standard Android Bluetooth menu keeps the discovered devices with some numbers oder characters that doesnt complain to the devices Name.

3rd Problem was my dab app. no one of the dab apps worked fine, only the reprogrammed dab app from zouzou is working. the only Thing that doesnt work is that my head unit ask for permission to Access the usb device if the head unit was in sleep and if i start the dab app always. Xtrons Support said the Problem is known and theyre working on it... Does anyone have the same Problem with the permission for accessing the usb dab stick?

since i got the new update ( Firmware 20170407 & MCU 2.43.1 Mar 31 2017) the stuttering voice of Google maps is gone.

I also found out since the new Firmware it is possible to download via Amazon Underground the navigon app as free Version. before the update, the navigon app wasnt found in Amazon Underground app store. I downloaded it manually but it wont start but with the new Firmware it works fine with all the free plugins.

another "Problem" was the VPN Connection. If a VPN Connection wants to be created there must be set a Password oder a pattern to unlock. The Screen wont be locked but the Password or pattern must be set. But the damn Thing is if you choose a pattern as unlock and save the patternand you want to Change some Setting at the vpn Connection the Setup ONLY accepts an Password with characters or numbers and you wont be able to Change the pattern because you cant get to the menu for Passwords and pattern. So i was "locked out" i installed VPNcilla for adding a new vPN Connection and it works.

Later i wiped the System beacuse the Firmware update and didnt that mistake again and choosed a Password with numbers.

Thats all for my first Post :) i hope it helps

I hope the Echo Problem will be solved because here in Germany calls without Hands free can be expensive :P

I also would appreciate if spotify can be controlled by the Buttons on the steering Wheel. My Buttons are up and down but the tracks at spotify were controlled by Forward and backward and These Buttons are not available on my steering Wheel.

greetz from Germany...
