The distance, current speed, maximum speed, average speed and odometer are not correct on my rides. The wheel calibration is set correctly, as is the installation with the distance between the sensor
I bought this computer in July, 2014. It worked fine until 3 days ago when I hit the mode bar to get to the clock before my ride. The computer went blank, then went to all "8"'s, then back to normal except all my data was lost, i.e., odo, art, etc. The only functions that show up as correct (oddly enough) are the ride time, and stop watch (total time of ride). The computer is in set up mode and the battery (cr2032) should be okay.

It sounds like your computer reset itself. This may be due to a sticky button, as most computers are installed at the same place where folks have their aero bottles. Some of the nice sticky glucose liquid runs onto the computer face when you drink, gumming up the buttons. Try wiping your computer face with a hot damp (not dripping wet) rag. If this is the problem, the hot water should remove the sticky stuff on your buttons and allow your computer to work properly.
