Your headunit needs to be properly grounded. The factory black wire that goes into your wiring harness may not be sufficient enough for your radio. Creat our own ground.
ok thanks alot...
Yes, this is true. Find a better ground. Best to have clean metal to metal contact, to be sure sand it down well.
