Garmin mapping software comes with a security number. You need to contact Garmin and they will give you this number, if you purchased your maps through them or an authorized dealer.

It's called an Unlock Code, when you download a map from Garmin it atattaches an unlock code, this code is very longand a combo of numbers and letters (mine is 25 digits). You should be able to look at your download from "My Garmin" and the code will be in there It might also be under "Dashboard at the My Garmin web page.

I have bought a second hand garmin, and the owner gave me the manual and free US navigation map. Recently he also provided me the 25 digit unlock code, but I cannot register or unlock maps, cos when i try...


The unlock code he gave you must be the map unlock code. IF it is you can unlock the map without registering. Details of how to unlock your map are at http://www.fixya.com/support/r6197735-no_detailed_maps_found_support_routing
There's more information there than you'll need so skip to the paragraph on unlocking the map.

If the previous owner deletes your satnav from his garmin account you should then be able to register it.

My GPS keeps saying cant unlock maps after i already loaded maps on it


The Garmin Maps require a map unlock code in order for the GPS to be able to open/access it. Since the maps are copyright protected by Garmin you should of recieved the unlock code from Garmin when you purchased the new map update.

When the "no detailed maps found that support routing" screen comes up it covers any of the icons, so I'm unable to do anything.

Unable to unlock new maps


Where did you download the Australian maps from? If from Garmin, contact Garmin for the unlock code. Maps have to be unlocked to a specific unit.

If you downloaded the maps from the internet, you will still need to contact Garmin for an unlock code.
