Hmmm, downloaded the zip file, extracted, burned CD. Did the upgrade. Minor panic after it processed the update 100%, rebooted, and came up to the Enter Security Code screen. Could not do anything. Could not extract the CD. Gave up, turned off the 430N, turned off the Jeep and went inside. About an hour later I went out to make a run and when I turned the radio on it came up, defaulted to AM. Hit SAT and it was working. Hit NAV and had maps. Everything seemed to be working.
Made my run and when I started home I punched HOME on the NAV and it started routing me home. Everythign hunky dory. While going down the road I decided to take a short cut which would normally result in a "recalculating". As I made the turn the map hesitated, screen went blank, came up to a black screen with Garmin while the unit rebooted. Map came back with "Calculating 99%" and froze. Remained that way all the way home. BACK button did not work. Hide NAV still worked and the radio screen was okay but even after turning the vehilce off removing the key and turning it back on it was still stuck at "Calculating 99%".
Turned it off, went in the house and waited about an hour. Went out, turned key to ACCY, turned the 430N on and hit the NAV. It was at the Garmin boot up screen and in a second or two the map came up and the "Calculating" was gone and everything looked normal.
I guess my unit gets really pissed of you don't follow her routing instructions.
Will somebody else try routing and then make an off route turn and see if they get a recalculating or a lock up.
