I have a nuvi 760. Reading elsewhere I think I can put the unlocked image named as either gmapsupp.img or gmapsup1.img in a folder named Garmin on an SD card. If I want to leave my present map of US in the unit, can I just de-select it and use the new map from the card or do I have to replace the detail map in the internal memory? Sorry to be such a noob guys, be gentle won't you?

Hi All. Sorry to show my lack of knowledge... but I have a Nuvi 765 and want to put the latest 2014.20 on it.
Exactly what files do I need to copy/replace onto the Nuvi 765 in order for it to work properly.
I assume I need an "unlocked" img of the map itself correct ? But specifically which JCV file works and do I need a new gmap3d.img file or others for my specific nuvi unit ?
I seem to recall you need a new version of each file that is compatible with each version of the maps.
Thanks in advance.Last edited by timp4411; 2nd October 2013 at 04:16 PM.
