Hi
I have the F310BT with the new CNSD-130FM Software Update and Pioneer says it behaves now like the F320BT
I also installed the Apps clock, video player and image viewer all of them work fine for me.
U cant change the Background of the Radio, u can only choose an Image for the Startup Screen.
The apps like clock work fine, u must install them on SD Card.
Turn on ur Radio go to the application Menue and start it
