Hey guys teh handset of the VHF radio on my boat is buggered it seems. The external speaker turns on and I get a bit come on the screen when I first turn the speaker on but no display and none of the buttons bring anything up. The red distress button lights up but that's it. The insulation on the cord is all falling off so I think it needs replacement. Problem is they don't seem to exist any more.

Any suggestions where I might source one or am I better off just to buy a whole new radio?
