I hope you guys can help me out. I just installed 4.001 update that a purchased from a seller off ebay who has sold hundreds of these on sd cards.I went thru the process of installing it on my pioneer avic f900bt. I installed the program but when I started it up is was stuck on the system start up screen then rebooted itself to the pioneer screen,It did this twice. I then pushed the cd/DVD player button and it played the disc in the unit. I then went back to the main screen and a ffuierror popped up. I cut the car off and turned it back on now I can't access anything the error message ffuier
