If thats the case... How do I fix the card? I cant just copy the files to another card..
That would depend on regular SD Card vs mapping card ...
A regular SD Card might have an issue with the Matrix folder and/or contents ... in which case a different SD Card would be needed ...
A mapping card could be corrupt by accidently exporting Nav data to the mapping card ... in which case you would have to call the mapping card company for advice in how to possibly clean the corruption ...
The 1st issue at hand is to determine if the error popup is caused by a corrupt SD Card, a corrupt Waypoint in the unit memory, or some other gremlin we need to track down ...
