My 2001 380 DA has the original Ray VHF220. It has failed finally and I am looking to replace. As I understand it, the model 220 and the dinosaur that it is, were much larger in physical size than current models out there. Once I decide on a radio, I will need an adapter plate to mount. I was quoted $60 for a plastic mounting adapter (custom), and while I understand it is custom made, that seems a bit high for a plate made of acrylic. Any suggestions on a source that would be a bit more reasonable once I decide on a replacement unit? I am not interested in starboard.
