After having my amplifier repaired and resetting the GPS to the proper current location, it will operate correctly for about a week or so and then suddenly show that I am in a location miles from where I really am. I can use the menu and site position process to bring into correct status, but then it will shortly jump off track again. I tried cleaning the disc and resetting but neither corrected the problem. I would prefer not to buy a new disc unless that isthe only solution. Any thoughts.
