I've browsed through the pioneer site as well as various other nav sites, and I can't tell the difference between the 3 different models that Pioneer offers [next to the fact that one offers a screen and another doesn't]. The three units are: NAV-SYS610T, NAV-SYS910DVD, AVIC80-DVD For those that own the individual units or have reserached this before, can you answer these questions:

1) which one is touch-screen compatible?
2) which one plays dvds as well as navigates?
3) which one has an input for a rear-vew camera?

Any other descriptions/reviews are welcome

 

Well, I can tell you that the two SYS models include the AVIC80-DVD. That is the base GPS navigation system AVIC80-DVD. But, you need a display to go with it, by itself it's useless. The 610T system is the AVID80-DVD PLUS the 6210 Touchscreen display. The 910DVD has an in dash display with a CD/DVD player built in.

From what I have read, if your display is touch screen then the AVIC80 can do touch screen. The 610T does not have the ability to show DVD movies directly, you'd need another DVD player. The display in the 610T however does have two AV inputs (one especialy for rear view camera). I am not sure about 910TDVD.
