I have a TomTom One 30-series with 1GB storage (yes, an oldie)
I've updated the NavCore to 9.510 and it works with the "Benelux_900_4602" map.
But I can't get a V10-map working.
I tried:

• "europe_north_1gb_1005_8767",
• "europe_north_1gb_1010_8892"
• "Europe_1GB_North_1010_8950".

I updated FastActivate itself from within the program and updated the meta from within the program.

Fastactive says:
Incomplete Map(s) "": Europe_1GB_North-101576.meta => .dct ERROR

What am I doing wrong?
Any help would be appreciated.

My device Info (from FastActivate):
ttgo.bif:
DeviceName=TomTom ONE
DeviceVersionHW=ONE (v8)
DeviceSerialNumber=PBxxxxxxxxxx
BootLoaderVersion=55022
ApplicationVersionVersionNumber=9540

CurrentMapVersion=0.0
ttgo.bak:
DeviceName=TomTom ONE
DeviceVersionHW=ONE (v8)

ApplicationVersionVersionNumber=8010
ApplicationVersion=9369

CurrentMap=Western Europe 845.2666
CurrentMapVersion=845.2666
ttgo.ori:

DeviceSerialNumber=PBxxxxxxxxxx
BootLoaderVersion=55022

CurrentMap=
CurrentMapVersion=0.0

Map(s):
K:\Europe_1GB_North_1010_8950\

Storage:
Size 977MB, Free 315MB

The only maps that can be activated are the ones that have a meta code released on the following page:

topic20611.html

None of the maps you mention have a meta code

Woeps, my bad, forgot to check if there was an actual metacode.
Tried a 995-map and it works like a charm.
Big thanks, fredderf!!
