Thread: How To Get Your SD Card ID in Your Garmin Device

@diegoand
I know naught about Honda car satnavs, but it seems you may have several problems:

1. Garmin units read FAT or FAT32. Maybe RAW is not recognised at all. Try again with the second sd formatted correctly, if that doesn't work move on:

2. The detail map (gmapprom.img) is locked to the SD card, that is the files Gmapprom.unl & grmn0.gma are specific to the detail map and the SD CID: That is overcome by unlockers such as gimgunlock which unlock the map and remove its GMA protection and then your map should then be able to be used on any other Garmin unit or any other SD card. Conversely, another unlocked detail map may be used on your SD. That much is fact, the rest is not necessarily.

3. Your satnav is requiring a password to prevent another SD card being used other than the OEM card. I should think the unit sw checks the CID to confirm that it is one that has previously had a specific password entered. Mind you, this is my conjecture, but seems likely.

If you are prepared to take the risk, you could back up the 3 files gmapprom.img and its associated unl & gma, then remove them from your original card and copy a new unlocked map as gmapprom.img. The unit should still recognise the sd card id and the unlocked map will work on both the sd card and therefore the unit. Again, my conjecture, but if that doesn't work you should be able to copy the original map image with its unl and gma files back successfully.

Otherwise, search around and post over in [Only registered and activated users can see links. ] for help. Good luck.

PS: I see you've also posted here: [Only registered and activated users can see links. ], probably a better spot than car nav systems anyway seeing you're getting lots of expert attention there.
