The Samsung version saved me from having to go back from a community 2.3.4 to an official Samsung version. I had assumed the community version would have the Samsung Bluetooth stack, but I was wrong.
Your version works fine with the Audi BTA 1560 (pre-09/2008 A6). It is even bug-compatible to the Samsung code. The BTA occasionally shuts down or goes into a reconnection loop just like it does with the Samsung code (this did not happen when I had a Nokia Symbian phone). Of course I would appreciate a workaround but I see no way to find out what makes the BTA barf
A last question - am I right to assume that the installer app needs the paid app just like the "Bluetooth SIM Access (Trial)" does?
Thanks again for writing this!
