I have E350 that i would like to install the Viseeo bluetooth option or the equivelent MB option in. The car does not have the phone cradle or the UHI connector in the center console. I spoke with a representative at a local dealer and he quoted $650 if the car was prewired for phone or $2500 if not. The MB rep from MBUSA told me that if my car had the TeleAid option, which it does, that the car is prewired at the console. Does anyone know how to access the MOST bus through the center armrest?
