Thread: Looking for Turtoial for reading out 10 digit Garmin Unit ID & SD Serial No. for Garmin 430sx

Hi Lolypop000

Sorry to ask but my Garmin 440SX has only an SD Slot. Is it still possible to read out the 10 digit Garmin Unit ID ? I assume that is difficult.
I have some Serial No in the back.

There are few methods to determine UnitID without connecting it to computer.
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.

I will try the registration thing,
sind it cam with a build in map and I don´t have an SD card yet!!

Thank you.
