Hey Guys I'm looking and a new nav. for my B5.5 and debating between the Pioneer f700BT and F900BT. You can do lots of hacks to them which makes me happy. Anyway I came across this thread with a deal. I checked it and its still active, and it's from an authorized dealer. check it out if your interested in this unit.
