Hi
I have just installed a RNS 310 into my Mk5 GTI, and everything work fine apart from the Phone option, whenever I press the phone button the head unit just mutes the sound, I have tried to look for the RNS 310 over Bluetooth but is not pairing up. Does anyone here know if I need to activate the bluetooth feature for the head unit with VAG COM. I have checked the Firmware version and it's running 0357.
