i have the F900BT map version 01000600 Version 2009000, how can i update the firmware to a better firmware so i can run igo 8.3
look at the FX3.1 mod over on avic411 dot com forums... If you run that then you can use any map/poi for 8.3 (including latest 2011 NT,etc)
regarding F920BT which is EU model similar to X920BT in US, this actually does not use IGO for navigation, but pioneer's own branded nav app.
You can use CNSD-210FM to update to latest...
Again, look at X-series forum on avic411 dot com
