Garmin Zumo 400 Sat Nav. Bluetooth Adaptor?
Is there an adaptor for a garmin zumo 400 sat nav to connect from the audio jack plug to enable Bluetooth connectivity? This is for connection to a motorbike helmet ear piece. I basically want to use this Sat Nav whilst on my motor bike and when I bought the Garmin Sat nav I was told I could buy an adaptor to convert the base unit to bluetooth?
