The horse is dead but I will beat it anyway.
Bought my son a 2013 Ford Edge Limited with a sync 2 system (MFT) from the wife of a neighbor who passed away. He bought it new. It had factory navigation but it won't read the navigation card. The display says "Insert navigation Card". What I think happened is he had it in for service and they updated the system to 3.6. I think that's where the problem started.
In the Bezel apim diagnostics under navigation it says "Navigation Application: unknown", "Map Database: unknown".
Before I did research on the problem, I thought an update may solve the problem, so I updated it to 3.10. Downloaded the update from ford. It installed with no problem but the issue remains. I keep my vehicles perfect and I find it unbelievably irritating that is doesn't work. Any advise on how to fix this issue with out a trip to the dealer? I don't want to sink a bunch of money into it for an obsolete system. Like I said, I find it unbelievably irritating it doesn't work.
I did a master reset multiple times.
Disconnected the battery forever.
Inserted a SD Card with music on it to be sure the card slot is working, it played the music fine.
I know someone at a Ford dealer who gave me two new separate map cards to try before buying one.
Nothing!
