I have an '07 with the Monsoon stereo system, and lately I'm having different noises coming from the speakers (when stereo is on AND off), different speakers kicking out, and for a while the stereo would just volume down to zero, and not be able to be turned back up again. It's really a bunch of gremlins! Is the head unit fried? Can I replace it with an '08 model with an aux jack (07 has source button, but no aux jack-really!?!?)? Is there a good place to find used Monsoon head units? Thanks in advance!
