Purchased two of the com-4 to try out. Installed them tonight and walked down the road they worked for about 200 ft then became stat icky and then lost connection which i thought was pretty good, i do get two fm stations. have not connected bluetooth yet. i used scotch fasteners rather than the mount with two screws that came with units as helmets were to thick for screw mount to work. we will get out riding new years day by the way it will be quad riding and i will update.

 

we finally were out riding new years day, The com-4 work great you do hear engine noise but no wind noise. it was good experience.
