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 ffuierror pops up on the pioneer screen now.Has anyone had experience with this and what's the best way to fix it? Should I try to reinstall the program again or no. Thanks in advance everyone.

I bought my F7010 update on EBAY as well.. I would suggest contacting the seller.If he is the same as mine he was exceptionally helpful in getting me through the process.

I am having this same issue with my f900 and eBay update. Seller is trying to help me figure it out. If I figure it out I will post up.

Anyone figure this out? I am stuck listening to CDs in test mode. I have tried re installing several times with same results. Help me, I miss my satellite radio.
