i can get both at a good price right now, but the z2 is still twice as much as the d3. i dont watch dvds in the car, i had a d1 before and that worked well for me. Is there anything justifying the z2 over a d3? i have all my songs on my ipod so i never use cds either. So i guess it comes down to the mapping and interface. Its it that much nicer on the z2?

If you really plan on using your ipod that much, stick with the D3. Its ipod interface is MUCH faster

And the D3 can play iPod video through the iPod interface
