hey all, new guy here. i was pulled between the z2 and the d3 but i am going to go with the z2 since it has the built in hard drive for gps. anyways... i have a couple questions.

1) what is the part called to make my steering wheel controls work?

2) can i play the gps and/or dvd while driving on trips? if not, how do i fix this?

3)is the price difference worth if for the z2 compared to the d3? thanks all

1) pac-swi-ps

2) it has to be bypassed. there are plenty of threads on how to do it

3)two totally different machines, but probably not worth an extra $1,000
