my overhead is reading all goofy. it's all scrambled. and it's intermittent. somedays it's great others it sucks. i'm guessing it's the unit itself but figured i'd see if u guys had any other ideas.

 

Come out real easy with a BFH. Then hit e-bay and find yourself another one.

My 12V doesnt have the compass/temp but I sure would like to have it. Been thinking about getting a rear view mirror from a chevy (the ones with the temp and compass built inot the mirror.

 

i agree with dr evil bfh then replace,yeah mine acted wierd a while back found a article to fix the compass.had to drive in a circle at 25 mph got dizzy then it started working,other than that no problems with the overhead
