My Head Unit has stopped playing. The other day i went out to get in my Jeep and the radio did not come on. I pressed the source button and the radio came on for about 3 second and then shut back off with one beep. After a reset thinking that would clear it up it does exactly the same thing. wont play the radio, media aux nothing. no lights after 3 seconds. Ironically when i shut the ignition off the i get the typical 3 beeps. Has anyone seen this or anyone know what this means or how to fix it. Was a good player up to this point.
