My battery failed twice in a short period and since then I have a new car, and the camera is working but not the maps. Is there a copy of the program to get them working (Australian maps)?
The only thing I can recommend is a download of the latest version of the software. It's possible that the version of the software you had was corrupted, therefore resulting errors. Errors might appear when apps are not closed properly. This happens with computer and devices too. Use the link posted below to download a copy of the application (latest version) to test it with your maps.
