If you have a locked map on SD card you can find unlock code inside .img file or in .unl file.
This code can tell you your UnitID.

If you know unit serial number you also can get an UnitID. Go to my.garmin.com and select "Register your Garmin product"
Registering your unit you enter a serial number and you'll get an UnitID.
