I want to update an old TomTom one.
Here are the specifications:

Appl. 8.415 (1240/090818)
System 344750
64 MB RAM (available 21.2 MB)
GPS v1.20, Boot 5.5136
Map: Western_and_Central_Europe_2GB
v825.2157

I want to install the map Benelux_965_7250 (no meta for Benelux 970 yet).

Can I just patch the TomTom with FastActivate, or do I need to upgrade bootloader and/or navcore first?
