I ran into an issue earlier today. I was pulling my head unit out to take a peek at what inputs i had on the back and then promptly re-installed it back to where it belonged. a few ours passed and i went back out to start it up and leave work for the day. i noticed that the security light was on and my radio was off, and after paying closer attention i noticed my 4WD selector flashing and my abs, park and a few other lights flashing. when the radio is unplugged the issue goes away. now ive read about how to rest the the theftlock on stock head units but mine was purchased with an aftermarket radio in it. any ideas?? it dosent affect driving any and it still starts up whether the radio is plugged in or not, but id really like to have my radio back. Any help is appreciated!!
