I don't think this has been addressed before, but I apologize if it has. The CD player in our 2006 1800 trike sometimes hangs up when changing CDs. Everyone asks why in heaven's name would we use CDs rather than an M3P player when we can play so many more songs. We can use the M3P with the AUX switch and it's fine except for one thing. The volume has to be turned up as high as it can go and it still is not really very loud. Does anyone else have this problem and if so, how do you get the volume loud enough? Thanks for any help.
