Stereo was working fine. Was listening to XM while driving, and then on Accessory for about 10 minutes. Went to dinner. Got back in car and No Audio! Stereo seems to be fine otherwise - turns on/off, I can cycle through components, change channels, HFL even works to make or answer call but no audio. It's like I hit some secret mute button while ignition was on Accessory. Any ideas? Just purchased it after my 3-year lease was up, so if it's a replacement, it's my wallet. Thanks
