D1,N1 or N2?

Been doing some heavy reading here on the avic units,  anyway, a great forum.  I'm not clear on a few differences on these, so please forgive the probably dumb questions, since I dont have the actual unit yet.  I was about to buy one of the Pioneer D1 nav units for my landcruiser which has plenty of room in the dash,  and now am not sure that is one to buy.  I liked the fact that it had 2 media slots, but I was suprised to read that the D1 won't play a movie dvd?, and none will play them in a moving vehicle (without modding).

Now I'm thinking maybe the N1 is the better choice, but will it show the map scrolling if the nav DVD is not in the unit?

So what is the concensus on the three models, since they are all avail on ebay at around the same cost. Thanks

I'm on the MS gulf coast, a bad place to be this weekend thanks to Hurricane Katrina

I've been looking at the Eclipse units too on their website, think I still like the pioneers better.

i had a question about this. after i program the route, and eject the disk, what if i miss a turn, or take a detour of some kind. can the system recalculate the route without the nav disc in? i dont want to have to reinsert the disc everytime i miss a turn or something

thanks in advance for your help!

The memory navigation stores mapping around your original route and will re-route you back to the original route if you miss a turn or stop somewhere else.  Exactly how far you can go off route depends on the map density of the area (I think they said between 3 and 12 miles off the route.)
