It came with Route 66 navigation software.

I am getting Fatal Exception errors that indicate a software problem and reinstalling Route 66 on another and the existing SD cards hasn't helped.

I was wondering if anyone could recommend a ROM image that would be appropriate. I'd buy WM if need be, just appreciate ppl's opinions!
