Which is better? Which would you prefer? Reasoning?

 

D3 has a bigger display, doesn't lag like the F900, has a great user interface and I think its a better unit. The only drawback is that you can't run Navigation and have a DVD in the slot at the same time. Not a problem if you have an Ipod with video. Also, the F900 has bluetooth which is kind of nice.

My choice is the D3 because the F900 pissed me off so much that I just walked away from it.

 

sw33t... so I just got an Avic-900BT as a gift.. what to do what to do! lol ;]
Audio and Video here i come ;]

 

Well, if you just got one then I would just keep it. I am just bitter because my F90 was the very first one in Western Canada and so it didn't have any updates. It was slow and laggy and extremely gaytarded. With current updates, they are much quicker and can multitask better.

 

have a avicd3 still installed.. works fine.. could prolly get 600$ outta it since its still new in box no? think it might even have a warranty ;p
