Hi, first sorry for my English, I'm updating my system providing avic F920BT, the procedure is as described on avic411.

The problem is that I can not even install the update from the original pioneer site. Put the SD into the system but not part of anything automatically. If you open the sd from the gaming Munu leave some tracks incomprehensible. I read somewhere that SD could be a problem, I tried another brand ScanDisc always the same, but to no avail. I wanted to know if this problem can be a problem with SD or a system problem, as even the coupling of the signal is outrageous.

Thanks for the help good day
