Gamin Nuvi 1250 - where is the map img?

[MonoJoker]

Trying to look at updating a mate's Garmin as per subject but I can't see the maps img file - usually a 120-150 meg file aren't they? On my Win mobile devices it's always just in the Garmin root folder but not on this device. I've got myself the 2010 Aus&NZ map img file plus the map ID ready to go. Can anyone help with this?

Cheers
LT.

On new nuvis 1xxx, map is in hidden "System" folder usually named "gmapprom.img".
In Explorer -> Folder options, turn on "show hidden and system files" and You'll see it.
If You want to put new map, backup old gmapprom.img, rename new as original and copy it in this folder.
If map is locked, put unlock key in gmapprom.unl file in same place as .img file.
