is there a connector to where i can plug in my blackberry and play music? like a cord or something similar to the i-pod hook up for my d3?

Just get the Bluetooth adapter and do it that way.

the cord you want is 3.5 to 3.5 aux cable, one side plugs into the blackberry's headphone jack and the other plugs into the aux in on the front of the AVIC, i dont recommend using the bluetooth module for audio if your picky about sound quality as you will lose some sound quality due to the compression that the BT uses.

Why? Use the sd card, usb or cd/dvd.

why not, the blackberry already has the music on it, why not use it, also, i use my BB hooked to the avic to listen to stuff i get E-mailed, Pandora, slacker radio, it would be a pain in the ass if every time i added music to my BB if i also had to burn it to a CD or add the music onto an SD card, if the music is on CD or SD then what happens if he want to listen to it out side of the car, say at the gym or something. it suck to have to keep track of different music on many different places, especially since my phone is with me 100% of the time

use a usb to mini usb. the same cord you use to put music on your phone. I use it on my 4000ib and once i install my f7010 (expositor piece) i will try it on there
