so when i turn my truck on, the headunit comes on, and attempts to fold down. once its at the bottom, it turns off, and folds back up, and then it will try ot re-open, and then it will close again. it keeps goin this until i shut the truck off. if i time it right i can get it to stay shut by hitting the Open button, so ican use the radio at least, but if i hit the Open button, it will start to fold down, and then shut off, and refold. any ideas?
