Radio stopped working. Fuses are good, what could be the problem? All other devices in car are working.

I have the same problem with my 2006 kia rio. Have you found the problem that made you radio stop working? Sometimes the radio start working and stock again after a few minutes. All lights are turned on on the radio, everything looks fine but no sound comes from the speakers.

What you could do would be the verify the power & ground going to the deck, if both those are good than it sounds like an intermitten internal problem with the deck. If that's the case it may be cheaper to replace it with an aftermarket deck than repairing the OE one.......

Ya aftermarket decks are infinitely better than 99% of stock radios anyways. I don't understand why they put POS stereos in new cars...even if it is a Kia
