Hi guys,

Is there any option to upgrade my AVIC-F920bt to 3.0 version?

I'm from Poland so I need European Maps...

Most of all I want new firmware features, not exactly newer maps (but it will be nice )...

Thanks for your help !

or maybe

can i upgrade my F920BT with F940BT 4.01 fw file ?

Anything f920bt related is pretty much dead on this forum, don't expect replies
