have you connected you parking brake cable?

spiceweasel, thanks for your post, well no i can play videos too, and all option are now ok, i use a tutorial found on youtube, with search text "bypass F900BT", now i need the sd "A" from cnsd-300FM. anybody know where i can find???

just connect the parking brake cable to the ground of your radio..

the cnsd-300 fm doesnt help you because it must be activated online with a special code on the pioneer website.

first make a complete backup

then you can play with different versions avaliable like fx 3.1 oder the hybrid version 4 and add newer maps
