I have tried all of the recovery items except the last post from Neil. Just to recap My nuvi worked great for several years 2 weeks ago it got very sluggish so I shut it off and turned it back on and it never goes past the garmin screen. I can load software only by holding my finger on the top left screen and that is it. My computer never sees the garmin files. All I am after if possible is to recover my mileage logs.. So I have the right car and the right keys its just not starting so far..
