Just installed the latest Pioneer AVIC F900BT. This replaced my Radio 10 6 disc changer (sorry sold it for $ 300). This has great features, Navigation, Bluetooth phone connectivity, DVD Player and most importantly more watts for the speakers. It sounds alot better. I also added the rearview camera which utilizes the screen. It is mounted under the license plate, I plan to move it above the license plate.
The only thing I have noticed is it is slow to boot up, but the MSN live feeds are great for traffic updates, weather, gas prices and local movie times.
I just installed the 4smartcar.com bezel, it fits perfectly and looks great. Also just installed the Diamond D3 500-4 Amplifier and Pioneer Premier Speakers TS-D602P, Pioneer HD Tuner. There's alot of room behind the driver's seat, if you notice the driver's seat doesn't go back all the way.
