Thread: Honda Goldwing 2006-2008 Navi GPS Firmware Update Versions 4.60 & 4.70

If there is nothing on the card for the unit to read that message would not seem surprising perhaps? As to the other card(s) you tried, were they formatted with a PC or Mac? Some methods of formatting in FAT32 (there are more than one way, even with windows) are not easily recognised by some garmin units. I'd be trying again with the new card with the appropriate fw and img files on it (without reformatting first as the factory format should be universally readable). The other card(s) you tried may have been previously reformatted in FAT32 but in a way that garmin doesn't easily handle. You could try the older card(s) formatted using the tool from this thread: [Only registered and activated users can see links. ]. I've used RMPRepUSB to reformat sd cards and even a microdrive which couldn't even be read in windows and also for the internal memory of de-bricked nuvis. If you continue to have a problem with both the new card in it's original factory format and the older card(s) reformatted with RMPRepUSB and you are sure the instructions in Post #1 have been followed, you have at least eliminated the card format and need to look elsewhere for the problem.
