April 16, 2001hody guys! got a problem.... i just bought an 89` f-150 4x4 and its great excvept for one thing. the man that owned it before me put in an aftermarket stereo and i think that he did it him self. the problem is that whenever you turn the truck off it erases your pre set stations and the clock and stuff. any help would be greatly appreciated.
