1. Do a full Windows backup of your current Setup/SD card.
2. Download/extract & instal this Navcore to your SD card or internal, (Overwriting any commen files)
3. Download/extract & instal the v845.2649 Truck map folder to your Root memory and crack it (create 2 .dct files within the map folder) using FastActivate from here :- http://www.navitotal.com/forums/showthread.php?2011-FastActivate_09.07.2010&p=7867#post7867

Notes:

1. This dump includes the system file for bootloader 5.5260 which reads SDHC cards & works fine on ONE XL's but if you prefer to use another bootloader then DELETE the system file from the download PRIOR to installing onto the SD card.
2. This dump already includes a patched ttsystem file so you don't need to rerun THAT part of a cracking/patching tool.
