I have had my AVIC-F900BT for about a year and a half and just found this site, and so far it is amazing and I want to send out a thanks to everyone that makes this site work. It's almost as if my one head unit is now a dozen different ones depending on the mod package I want to use. As a long time computer enthusiast it is great to be able to mess with settings that were included originally but never made available. Thanks again and great site!
