Hello, I would like to use Eluder GT's CB radio, as well as the Intercom features and hear the radio through a headset. Now I'm looking at Yamaha's OEM accessory headset which is actually the J&M and I just can't see forking out 700 bucks to get myself and wife hooked up. Thats two headsets, passenger connection kit, headset connection cord, passenger ext. cord. So is there a more affordable option out there like the bluetooth headsets & do I lose some of the built-in features of the infotainment system going the cordless route?
