When I installed my nav and cdx I had to unplug the gauge cluster to install the vss wire and after everything was installed I checked my engine hours a few days later and it was reading only 15 hours when the week before it had 850 hours. Has anyone else had this problem or does anyone know if there is a way to fix it? Thanks.

I had mine reset too. I didn't do anything with my gauge cluster so I don't know what is going on.

Yeah, I didn't do anything electrical to mine and the engine hours kept resetting. I've gone through 7 clusters. This last one seems to be doing the job.

Mine has reset 3 times now for no reason at all.

I wish my odometer and hour meter would reset...almost 4800 hours and 216k+ miles
