ok i bought a 2001 xstar and 2day was the first time taking it out and when i went to turn the radio on the stereo lighted up but there was no sound?When i test drove it everything worked properly!The dealership winterized it for me so is there anything they could of done that could be causeing this problem?
If you have a perko switch make sure it's switched to both. Maybe you're amps are hooked to your other battery and it's isolated so you have no power to them.
I had the same problem in my 2000 and after troubleshooting everything I had to replace the head unit. I believe I had the Clarion 5645 or something like that, and I read afterward that many people had to replace it.
