i have a mariah 180 (97) with a jenson xc7100 radio cassette. want to replace this as it is a bit tired. it has big stalks for the volume and tuning controls, these are also used to bolt the stereo unit onto the mounting bracket. i'm not familiar with this format, they dont seem to be sold like this any more?????? i was looking to put a cd player in the boat, but the mounting bracket wont let me as the cd wont fit through the mounting bracket, how do you guys mount ya sterio's, any mariah owners out there??????????????
