Does anybody know if the hardware of the avic-f950bt is (about) the same as the 940bt and 930bt and/or it might be possible, to upgrade the 930bt/940bt to the 950bt?

 

If I understood it well, the 950bt has also the appradio mode for Android.

short answer: no - x50 series is different hardware from previous versions
