I have a garmin 1430LMT which has been working perfectly for years until I updated the software to version 6.30 a few days ago. It seems to start OK. It must find the sats because the time on the top is accurate. You can go into "Where to" and all is fine. You can go into "volume" and all is fine. I can go into "tools" As soon as I went into "map detail" and then backed out the system crashed and shut off. I pushed the power switch and it came back up.
I go into "view map" and it says ready to navigate but the screen has no map, the touch screen response is delayed for 15 to 30 seconds. Letting it sit for about 1 minute the 3d map and position arrow appears. I pushed the - and waited 30 seconds to hear the beep and the screen didn't do anything. I hit the back key and the main screen comes up with some artifacts on the right that are left over from the prior screen.
I removed the sd card and tested it out in my desktop. I was able to see the files and I checked the file system.
Any ideas?
