So travelling back from Watertown, NY to home. Running my 536, all favorites lists on and using GPS. Whenever I shut the car off I turn the scanner off,. Well, halfway home, I find out all of my favorite lists except the first ten are wiped clean. Reformatted the card, reloaded everything. Worked for a while, now all lists are gone again except the first ten. Anyone else experience this one? I am going to try a new card as well
