I have gone to the tutorials and have downloaded some tools. FastActivate (both), AutoActivate & TTCurrentConfig. Basically I would like to load new maps on the device. There are 7xx & 8xx versions of maps. Then I see multiple versions of the maps for example There are 850 & 885 maps collecitons and inside those North Americas has multiple map versions of the 885 or 850.

North_America_2GB 885_4088
North_America_2GB 885_4097
North_America_P 885_4097

TTGO.BIF:

DeviceVersionHW=ONE XL
BootLoaderVersion=55022
ApplicationVersionVersionNumber=8016
ApplicationVersion=9380
CurrentMap=USA_and_Canada

OK, how can Navitotal TomTom help you?
