I have been running 3.0 on my F900BT for a few days nows. I am not going to say where I got it, and I'm not going to upload it (yet) because I believe there is another member who is working on that right now.
Pretty much it is a big disappointment. The speed from the CE update is great, but nothing else has been fixed that I can tell. To make this short:
-Dial-by-name still doesn't work unless your phonebook is pristine
-The unit still swtiches to the Map screen when a phone call is received. If you look at JasonH's "F series vs X series" thread, Pioneer actually claimed that this was fixed. It is not.
-The "auto" setting for map day/night colors is still controlled by the system time, despite the fact that the x-series manual says this settings is controlled by the orange illumination wire
-The TTS voices are exactly the same. Samantha still sounds like ass.
-Presets can be changed from the steering wheel control, but it often skips more than one at time so i end up just using the screen anyway. Today it actually just kept going, and going, and going, and I had to turn the car off to stop it
-TeleAtlas maps just suck, around here anyway. I can't wait till the ezrider is hacked so i can use the NAVTEQ maps which 8.3 supports. I have them on my PPC with iGo 8.3 and they are far better than the TeleAtlas maps.
Thats all i can think of for now. I will update as I use the unit more, but as i said I think it's going to be uploaded soon enough that you all can see for yourself. Just don't get your hopes up, because the only real part thats worth a shit is the part most of you have already done (the CE update)
