Hello,

 

I'm torn on which of the two units to get. I will be installing the unit into a 2001 Accord and will be using an iphone with it. The options that I will get are the ipod, BT and the XM with Traffic. I live in the Atlanta area and have about an hour's drive each way to and from work, so the navigation with the traffic info is very important to me.

 

I was ready to pull the trigger on the D3, but I really like the idea of having the nav data on the hard drive of the z2. I'm also concerned with how well the directions work on the d3 after reading some negative posts about it. Does the z2 nav work better?

 

Any advice on which unit to buy would be greatly appreciated.
