New member- 2008 M3 Coupe Silverstone- luv it! First M3 also own 335 i coupe.

Installed k40 Calibre Radar System- utilizes bluetooth vs. hard wire- now have issue with cell phone reception quality. Anyone else experiencing this?

K40 tells me that the Bluetooth Kit or the TCU unit needs to be 1.2 or higher in the car- if so there sould be no issues? Does anyone know this information about the Bluetooth kit in the 2008 m3?

thanks
joe
