Got my headunit in and was working fine for 4 weeks now it goes for about 5 - 10 minutes then turns off and on off and on so doesnt work anymore. turn the car off and back on it works again for 5 - 10 minutes then turns off on again. I have pulled it all out and checkd the wiring and it seems to b fine ive cleaned all fuses and check most things i thought would b the problem but havnt been able to fix it. Any ideas anyone?
