You have an aviation unit and don't know what the map on the SD card is?
The map and it's associated files will most likely be unique to the card ID, not the device.
If you can provide the code in the UNL that map on the card can be identified. It's simply asciii text, use notepad or similar.
As for the device itself you could try contacting Garmin with the serial number and ask them for the ID.

All aviation databases (they do not call them maps) are stored directly onto unit's built in memory, not on SD cards. The map on the SD card is something which was in the unit when I bought it from previous owner a long time ago. It does not affect the databases in any way.
Using GMapTool I discovered the map is:
CN Europe NT 2012.20 ALL
PID 1
FID 2473
U: PJDUT-VWFGX-YLY2H-3RRS6-GJLQT
UNL: T4F8F8HKUMPBZLSD8W6GV5UJC
Thanks for any help.

Unit ID 2171088435 will be the SD card serial number
It could be worth looking in the following locations for the Unit ID
C:\ProgramData\Garmin\CoreService\Devices
C:\ProgramData\Garmin\CoreService\device_data_store.xml
C:\ProgramData\Garmin\CoreService\preloaded_maps.xmlLast edited by Boki; 8th May 2020 at 09:39 AM. Reason: removed unnecessary quote
