One function, apart from loading and running the navcore, is SD-Card support (to load the navcore from it). The bootloader is the file 'system' in the root of your TT.

Which modes are available depends on what Tom Tom includes in the navcore and the magic of TTuser. x50, x40, x40light, x30, x20, ori (see and this site) Use 'ori' to get the original look for your device. if you like, extract the original navcore-CAB file to internal flash, but do not overwrite any file, and remove 'system' (use Win RAR) Without basicpack, get the splashscreens (*.bmp) from your backup.
