Thanks for this, but I'm having trouble getting it to work.
I updated FastActivate, and then the navcore. I closed FastActivate and then I ran the map exe (Brazil 950.6492_Installer.part1.exe) and it didn't report any problems.
But when I start the device it uses the old map. There are 2 folders: "Brazil" (old map) and "Brazil_950_6492" (the new one). I tried deleting the old map but that just brings up a red screen.
After that, I restored my backup and tried again, same problems.
Running "My device info" on FastActivate:
ttgo.bif:
DeviceName=TomTom START
DeviceVersionHW=START
DeviceSerialNumber=GUxxxxxxxxxx
BootLoaderVersion=55282
ApplicationVersionVersionNumber=9510
ApplicationVersion=1234792.2
CurrentMap=
CurrentMapVersion=0.0
Map(s):
F:\Brazil_950_6492\
Storage:
Size 1884MB, Free 1420MB
Any help is appreciated.
