9w7 M bluetooth module problem
 

Dear members,
i recently installed a newly bought 9w7 (7p6035730 M) to my RCD510 Bosch(5K0035190) with 26pin RVC capable . I retrofitted the bluetooth module in my passat 1.4TSI 2010 which wasn't factory installed by bluetooth. I then coded the system with Genuine Ross-Tech Hex+Can cable (Vagcom). as you will see in the attached scan, I opened the can gate and installed telephone (77), then coded it. opened the radio and coded that too. opened the steering wheel and coded it to use PTT, to enable the voice dialing and command (mute button before).
the results where that the mfdsw shows the phone book as well as the rcd. Bluetooth audio streams songs from mobile but showing (bluetooth audio) only on rcd screen, doesn't show the song details nor the controls (pause, forward, reverse. all grey not highlighted). Now Mute button doesn't work neither mute nor voice command or dialing. . How to enable A2DP, and how does it work?
Another thing when i scanned radio got a fault code from the AUX open circuit, which i managed to erase by unticking the AUX monitoring from the radio codes (which is factory ticked ). Don't know why gets the fault code. so please guide me code the bluetooth module to enable A2DP, get the voice button to dial and command and tell me why the AUX gets fault codes

I went to a dealer shop to check, maybe i have done something wrong with programming, but he said all is correct and he didn't find why. he also said maybe A2DP isn't working, although this is a new module. Also phonebook on the rcd screen after getting the name out of it doesn't dial and shows astricks. do you know what can be the problem and help me with it?
Thank you in advance.

I see you've posted on the Ross-Tech forum. 9w7 M bluetooth module problem

See what those guys come up with?

Yes. I am really disappointed from trying to buy the latest model to get the most out of it, and couldn't get it to work well. I feel those Ross-tech guys really know what they are doing. After buying their cable (vagcom) and finding that it maybe the best in market, i really trust them.
