I want to install bluetooth car kit "parrot ck3100" on my V40-2001 with HU-1205 radio/gps system.
I don't know where pin connection of mute, and I don't know if i need other parts for completing installation.
Will shortly be carrying out same procedure with same equipment. Your parrot should just plug in the rear of the audio unit with or without patch leads and the muting is done for you by the parrot kit. Are you thinking of the Nokia Bluetooth kits where a mute wire is needed?
