I must be dense, but can someone post a detailed step by step instruction on how to load the China map (ver 2010.21) onto my Garmin nuvi360? I have downloaded the 4 rar files and unpacked them using WINRAR. I tried using FastIMG Unlocker 1.5 and it seems the program ran (can't tell). I copied the 2 gmapbmap.img and gmapsupp.img fiels from my PC to my SD card, but no map is displayed. I have looked at other treads on using GMap Tool, MapSource and Garmin Key Gen to unlock the maps, but nothing. PLEASE HELP!! I am very new at all this.
