Still looking for help I have read the file you wanted me to read thread you wanted me to. My main issue is that I can not get into the "NAV" pull down window to see anything , it just stays in "GARMIN" & never loads anything. I have researched this & can not find out why it is happening. I think it needs to be flashed. I got a updated Flash for the radio & it still hasnt changed my NAV window at all still stuck saying loading maps & nothing
