I have a TomTomRider model 4GD00. I am attempting to connect it to an FM modulater on my 2012 Kawaski Voyager. I've tried connecting through the bike headset option, the car headset option and the phone option. It does not connect. It will connect to my blue tooth ear piece on the bike headset option. The bluetooth version of the modulater is 4.2, is it a version issue that the GPS does not reconize it?
