I tried to update my Via 1425 and it corrupted the map. I was able to delete the files on my SD card. I did a reset on the device. When the device reboots, it says no map found. When I plug it into my laptop and run MyDrive Connect, it shows a map update. When I try to update, the program tries to connect however after a few minutes the program says that my device is not responding. The device says updating, but never finishes. How can I rebuild the map on my device?
