Bluetooth problem

Hello,
For a couple of months i have been using a HTC Touch Pro.
Since then i have a problem connecting my phone to my car.
I am driving a Peugeot 206 with a build in radio, and i have no problems connecting the phone to the radio.
However when i try to call someone i can here the dialtune over the radio but when the person on the other side picks up the phone the connection drops out and i can`t here anyone. Only when i press the speakeroption on the phone i can speak to the person on the other side.
The same problem occurs when i get called and i pick up the phone.
The weird thing is before i upgraded my phone to the latest official ROM-update i was able to call people and i could actually use my build in bluetooth car function. But now after the update i cant do anything anymore.
I`m using the following ROM and Radio:
ROM: 5.05.404.1 NLD
Radio: 1.11.25.01
There must be a way that i can actually call someone, let stand pick up my phone in my car.

BT SAP on TD2 problem

Hello all,
I recently purchased the TD2 and I encounter a problem with its BT SAP functionality with my car (VW).
It connects and works ok, but when I turn the ignition off, remove the key and the phone disconnects from the car, it doesn't reconnect to the GSM provider again. I have to go to Settings/Communications and turn the phone off and then on again in order to reconnect.
Has anyone encountered a similar issue?
HTC support told me that it seems the car BT is not releasing the SIM card properly. The thing is that my old prophet with a cooked WM6.1 rom (don't remember which one right now), worked fine, without any similar problem.
Any ideas?
TIA.
PS. Ooops, sorry, think I posted on the wrong topic.

PX5 Headunit WIFI Sometimes Won't Turn On

Hey, i have a wondefoo PX-5 Android Headunit 8.0, everything was working great but someday suddendly the WIFI didn't turn on (when turning the car on).
Since then, every now and then the WIFI won't turn on after the car was shut down, the problem is solved only if I restart the HeadUnit several times until the WIFI will come on.
I tried searching online but didn't find a problem as close to mine.. The WIFI does work but as I said only if I restart the HeadUnit.
When it's not working i just try to "flick" the switch from the OFF to ON position and it automatically returns to OFF (won't stay on the ON position for even a second).
Looking forward for your help,
Thanks, in advanced.
Same problem
I have a Dicola android 8.0 PX5 4GB/32GB head unit for my Audi A3.
I have the same problem as you discribe. The seller advised me to update the device but that had no effect.
I saw on Google more problems with those PX5 units. I seems to be the Wifi/BT module what causses the defect. Especially the low tempeture could cuase the defect. Not sure if this is the case but you are not the only one.

Erisin PX5 only Radio-App no Sound

Hello
I have a problem with my Android car radio, hope you can help. It's an Erison PX5 - LM MCU.
My problem is that the radio-app does not emit any sound and does not search any more. Other apps like Maps, Mediaplayer, Jetaudio make sound, only the radio-app doesn't.
Maybe someone here has a suggestion what else I could do or where I could look up something wrong. I already have an Android 10 ROM installed, did not solve the problem.
Other radio FM apps didn't work either.
I hope it's not a hardware problem. I love my radio .
My thanks also go to Alex from Alex Android Radio, who has already helped me a lot.
I hope for an answer.

Send it back for warranty once antenna connection validated as ok.

Hi everyone. I have a 8227L HU, android 10, 10inch for vw passat, full touch, chinesse, from Junsun, aliexpress.
I had some canbus problems, and the seller gave me the 8227L-8.bin file to update, now the canbus problems solved, but the radio tuner application is stucked, i cant change the stations, and i have no sound on radio. I tried to make the settings in factory service mode, but nothing. I think the firmware is not ok. Can someone help me with some advice? Or a firmware that is suitable for my device ? Thanks a lot.
