My radio is working fine though mate when i am not using the system. I am not too bothered about not being able to use the bluetooth...apart from the non-compatibility of my handset with the Nurrish system. Everything else is spot on...not seen a navigation system as comprehensive as this before. Most of the other aftermarket navigation units get a bit "confused" when they come to a bypass etc. U do know that once u have set the Nurrish system on a FM transmitter waveband, you can't listen to the radio at the same time as they are on a different pre-set waveband. If you use the radio, the navigation uses it's internal speaker instead. Don't think you could make the BOSE headunit and the system to use the BOSE speakers at the same time. PM Dave if u need further advice. It's quite easy to use once u have had a play around with it. Mike
