Display Problem on VIA 1605
My father has a 1605TM GPS. It recently started to show the configuration screen while navigation continues while driving. One time, after re-entering the route information and restarting navigation, the same symptom started in about 5 minutes. Sometimes, the drive can go for an hour with a problem and others it is just minutes. Is this something that a firmware reinstallation may fix, and if so, how does one do that?
