I'm not sure to be honest. Because it depends on partially what bluetooth module you have. There are two different modules. One is called a MULF which has both Bluetooth and USB support, and the other is TCU (telephone control unit). I have the MULF because I did the bluetooth and USB retrofit. Depending on what you have, then you would need to check that module for the software version. As far as how to check for the software version, I think you would need at least a D-Can cable and some software on a laptop to do the check.
There is a member on this forum that is more knowledgeable, I can PM his name to you if your interested.
