Query: Worked for 1st month then died - no response from Customer Support!

Worked OK for 1st month then stopped; devise now displays a msg to reset it which after following directions in manual carefully didn't revive it.Since Navigon no longer allows any buyers to call them (RED FLAG), sent Navigon's Customer Support a total of 5 emails requesting HELP over past 5 weeks. All I get is an OUT-OF-OFFICE auto-response (RED FLAG #2).I'd suggest buying another device.... too bad since it did a gd job for 4 weeks.If I ever get a response I will update this post.
