I have read all the pages of your message. But, unfortunately, not quite understand, how do I encode the radio?
I have a car produced in 2011. It was a BMW Professional radio. I bought at Ebay as you recorder BMW Professional and Bluetooth YUSB. BMW authorized dealers can not encode it - because they do not know how.
Periodic audible clicks even radio is turned off.
Hong is also very loud! YUSB like seeing, but not yet tested, since there is no cable (coming from Germany). Bluetooth sees my phone, but then connect the call can not hear anything! And no one can hear me! Bluetooth is also necessary to code? Or is it a radio problem? Thank you!
