I have a 2008 Jeep Wrangler Unlimited X with a factory radio. In the past several months it has started giving me problems. At first we unhooked/rehooked the battery and that seemed to have fixed it for a while. Then the display would work, but there would be no sound and the volume knob wouldn't register. Then for a period of time the radio would work, but we'd get loud bursts of static. Now it just shows display, will let you change channels, etc. but still no volume/sound. I have checked the fuses under the hood and have taken the dash apart and unhooked/rehooked radio. Any ideas? I may end up taking it to a dealer, but was hoping to avoid the extra cost. Any advice is greatly appreciated!
