Smokin'...have the same problem with mine...were you able to resolve? Thanks...

CD would not eject had to replace the radio. With Sony.

Well, it's now "when"! I was riding along when the radio cut out, came back on for a few minutes then cut out again permanently.
I have full diplay, can change am/fm/cd; channels tune, volume up/dwn OK, etc-- just no sound out of any speaker.

Have done wiggle tests, checked dash switch checked for loose wires, etc. etc. so now time to run the diagnostics, but will first pull maxi fuse and reset.

Will let ya know what I find.

yeeep just what mine is doing.....everything but the noise

Help! The HK unit on my 2011 SG seems to be locked up. When I turn the ignition on the radio display comes on and it appears to be on an FM station, but no sound. None of the handlebar controls work and I can't turn the radio off. Also will not eject the CD. Tried pulling the radio memory fuse, radio power fuse and also the maxi fuse. Same end result. Any ideas?

have the same problem. did you ever solve?

Cant be 100% sure without going into the radio, but those are the classic symptoms of liquid damage taking out the TMS320 processor.

I thought the HK radios were supposed to be watertight? Mine went out on me last week (luckily under warranty) and is in the shop now.

They are not watertight and do not claim to be.
They are extremely water resistant, but no unit (this or aftermarket) with a CD slot, aux port, USB port, iPod tray..etc cam possible be watertight.
Read the full warranty on most Marine grade aftermarket units. They will not warranty water intrusion.

anyone know of a cover? saw a cover on ebay , but it was only for aftermarket radios.
