D2 VS D3
#2
Buy the d3, the d2 is old and discontinued. You can find the d3 for less than 600shipped now adays. I bought one about two weeks ago. I purchased a d3, ipod cord, harness, mounting kit, pac swi-ps, and all the little connectors to install it with for less than $675 installed
If you can wait, D4 will be coming out within the next 6 months probably.
