When I bought my 2000lt, it had a Honda CB/Communication system mounted. It was tied in to the sound system and worked pretty good except for the whine when traveling. Tried playing with controls but didn't make much difference. My wife and I still like talking to one another while traveling so I just purchased a Sena SMH5 system. Any advice or info from anyone with the same unit? It looks to be very good quality. Any other thoughts?
