Just bought the TOM TOM Navigator 7 from a retailer in Sweden.
Its the 1OK0.054.01 delivered on a 2 GB SD.
The "Application version = 7.910" (found in the "Release file")
Trying to install the CAB file from SD or copying it to internal memory (installing it from there) gives the same error:
"Your device is not compatible with this version of TomTom NAVIGATOR 7"
My Diamond 2 is brand new (1 day) delivered with WM 6.5 from factory.
I have looked around quite a lot but it seems like no one have this problem.
Due to the fact that the Diamond 2 IS supported according to TOM TOM today it makes me quite...upset.
