I am trying to take the advise for removing files from my nuvi 3760T system file and putting the updated files on sd
my original map that came with the device are CN EUROPE NTU 2012.10 and CN Middle East & N. Africa NT 2012.10
I will change both to latest version to 2013
My question is which file to delete that belong to the old version[Only registered and activated users can see links. ][Only registered and activated users can see links. ][Only registered and activated users can see links. ]
1-as you can see the .dp and G2S and GMAPTZ.img files which one I can delete and replace with the new one
2- for the map files also I guess for the map gmapbmap.img is a must it is base map but the others gmapprom.gma and gmapprom1.gma should they be deleted and replce it with the new ones
3- files gmapprom.gma gmapprom.unl gmapprom.sum should I leave them as they are or delete them

Kindly advise
