Hi, I just tried to upgrade my F90BT unit to 3.0, but was unsuccessful. I got all the files, formatted it supposively with WinCE 6.0 (but it still said 5.0), copied all the 3.0 files on to the formatted unit, but it would not get past the pioneer screen. So, I decided that I would just forget it and get it back to 2.0. So I tried putting on the testmode folder I had from a while ago (not the new 2.3 testmode), I put it in the unit and it just stays at the pioneer screen! No matter what I try, I can't get it past that. The only thing I can get to is the blue service screen if I push the button
