Recently attempted an update with TomTom Home V 184.108.40.2065 on my MacOS. It updated the GPSfix and minor map updates. When the original 8 Gb SD card (USA/Puerto Rico/Canada) was reinserted into the 2014 CX-5 on-board TomTom nav, the on-board nav reads the SD card and then says “cannot find maps”. I have attempted everything...loopdir removals, save items from computer, etc. Nothing seems to work. On my Mac, I can see the entire SD file system, and the map folder appears to be intact. The Disk Utility also checked out the SD and found no corrupted sectors.
I’m tempted to reformat the SD (FAT32, naturally), but that would be the last act of desperation.
Does anyone have a clue how to solve this problem??
