Last December my D3 got stolen. I finally got my insurance money and bought a F90BT to replace it. I knew the F series had some issues, but I had no idea they would be this bad. My unit is supposed to have the 2.0 update installed. I didn't want to try any other navigation systems, because I was already set up for everything to plug-in play with pioneer units.
Here is my list of annoyances with this unit compared to the D3. I'm seriously considering selling this unit and going back with the D3.
1. Takes way to long for the backup camera to come up.
2. Unit still takes a long time to boot up with the 2.0 update installed.
3. Operation of the unit lags quite a bit. Kinda like a old computer running programs it can barely run.
4. No track up on 2D mode. Pioneer programmers must have been smoking something to miss this. I hear there is another update that might fix this. That would make the unit more usable.
5. In 3D mode the track arrow is huge. There is no need for this. However, I hear this can be modified.
6. In 3D mode you can't zoom out enough.
7. When searching for a POI I want to be able to type in the name of the place and have the unit try and narrow down my search as I go. D3 did this.
8. There is no way to have the navigation lady speak over the music. I don't want my music to mute every time she speaks.
9. No remote control.
10. The map moves in a jerky manner, and it takes awhile to register that I've already turned. The D3 was much faster in this aspect. Yes, I have the VSS wire connected.
11. The volume knob is almost useless. I know you can get replacement knobs, but another thing pioneer overlooked.
12. No motion sensors. I kinda liked that feature on the D3.
I guess I'll list some positives.
1. Graphics are much better than the D3.
2. Integrated bluetooth.
3. Ipod cable came with unit.
5. Shows elevation. D3 didn't.
6. Can be modified easier.
7. Like the D3 this unit is easily bypassed. I won't buy a unit that can't be bypassed.
Edit: I did play with this unit in the store, but some of these things you don't find out until you actually use the unit.
