scope

i'm glad it's not just me. im wondering if i can go back to my old disc's, as i really do need it working in some shape or form.

hi im new on here, i;ve just bought the cndv 100mt disc, and at first it worked great and i was very pleased! however now the screen keeps flickering and going off, then i get a message saying to insert appropriate disc! when i eject the disc, it dose seem quite hot. i really hope someone can help, as im going to be driving to germany in the next couple of days, and really need my sat nav working. many thanks
