I doubt that there is someone making bezels but let us know if you find some. Wired For Sound can get you the MRC-2 but they want about 90$ for them. They are in murrieta ca. I have the sony w/display on the transom and am adding the Access Technologies up in the bow so I dont have to climb in the boat from shore.
How about taken a look at www.ideasthatfloat.com there is another option.I work for this company and we have been building marine RF remote products for years. The latest is a piece call the i-rock it comes in two styles the Hub style that replaces the center cab (HUB) in the steering wheel and gives you complete radio controls it also can be mounted in a standard 21/8" gage hole. The other is a hand held keyfob remote that is also RF(radio frequency) not IR, which means you dont have to point the remote at the radio! It actually has a range of 100' or more. the best part is that its totally waterproof and it floats.E-mail me at bobc@hatch-it.com and I'll send you a pdf picture and the pricing. Its only about $150 for the reciever and remote w/holder.
have a good one.
