Thought I would post some info for anyone looking at AM/FM radios. Originally I fitted a GME GR200 and wired it into the Starcom. I then found that this is one of the most difficult radios to use on a bike. Buttons were small and wiring speaker outputs into the intercom is not best practice. As well navigation around the Bands/Stations could not be done on the fly. The other annoying issue was there was no external music input. Their next model has a AUX input with no controls. Again, it was awkward to select this option.
Came across a marine radio from Fusion and investigated its options. It seemed to be vastly better than the GME, so I bought one. It is roughly the same size although deeper, it has "Line Out" for connecting to the intercom, it is very easy to use for navigating and has large buttons. Finally it has a fully functioning Ipod interface. No I am not an Apple fan, but the wife had an older Ipod that she no longer used so I fitted it. Sound quality good, useability good, functionality good in particular the ease that you can scan for new FM stations. The cost about the same as the GME plus an Ipod cable. I have it mounted on top of the dash and being marine, it is waterproof. It also has a AUX input which I do not use. I have been using it now for 9 months with no issues.
