I just try to open Navigasi net Indonesia map those basecamp could not open it,
and i follow your instruction to use GMap Tool and it show up on Basecamp.

Garmin City Navigator ID map just to crowded when i see, is that everything showing on basecamp will show on GPS too ?

Ok so post #3 will erase the original NA Map and it will put Indonesia Map right ?
I plan to put those Navigasi Map as second map, can you give me a link about the way to add it on GPS

Your SP2610 so its basically 2GB max
What i still confuse is, how big storage at SP2720 ?
