Hello everyone.


I'm not sure that I am posting in the correct area or not, so If I am not, then I apologize. I purchased the Rosen MZ1010-H11 back in 2012 for my 2012 Mazda 3 and haven't had any issues with it until recently. The navigation unit in the radio is no longer working. Every time I push the "NAV" button now I am receiving an error message on the screen. The error message box reads "nngnavi.exe" 'nngnavi' is not a valid Windows CE application. I am forced to push the OK button on the radio and then the Rosen background just appears. I haven't removed the card at all and haven't messed with any of the settings. I relatively suspect that the card may have actually gone bad, but I'm not 100% sure. If the card did actually go bad, how would I go about getting those files back so that I can use my GPS again? I have tried using the naviextra toolbox but it's just showing the loading screen on my computer when I click devices.


Thank you all for the help!
