I have an official CNSD-100FM on my F900BT which therefore has 3.020200.
I also have Daftia's excellent mod.
Don't want to shell out another £100 for the 200 update.
A. Is there a way to make mine 200 map wise
B. Is there a way to upgrade the firmware is it version 4 ?
Please post instructions for for updating from CNSD-100FM etc.
