There are few threads about adding bluetooth to the R. I just want to make that I buy the correct part.. I used a torx driver and opened my center console and found out that I am pre-wired because I saw a 10pin male connector and a connector for an antenna inside the console but I did not see a cradle ?? Do I buy a Mercedes Benz Bluetooth MHI Adapter B67875878 or a V60 BLUETOOTH CRADLE ADAPTER B67875856 or something else.. I have a blackerry curve.. Thanks
