problem with side view

My 997 has lost all my waypoints and maps. I can make a waypoints and as long as the power is on it will stay once I turn the power of its gone. Has anyone every had this happen or know anyone around here that can work on one. I hate to send it off at prim crappie time thanks for any help.

I also have the 997 and never had that issue. Did you try to reset the SD cards? Maybe pull it off power all together for a day or so. Otherwise sorry cant be of any help!!

if you havent already post this on the electronics forum
