So i know that there is a 10gb difference. No big deal. I want to know if there are any problems with the 20gb units or the 30gb. Whats the low down on them? I am referring to the ones with Navigation. Thanks, Matt

 

I think the 20G came in the 07/08. I believe the 30G is for the 09's. Not positive on this, someone correct me if I am wrong.

 

30GB actually started coming out in some late model 07s
there is no difference between the 07 and 08, (other than some have 20GB drive, and some 30GB drive)
09s have an extra chip for iPod communications.

As for difference between the 20s and 30s, none really.

 

Thank you for the correct info!

 

what is needed to connect an 09 mygig to an iPod?

 

a cable with an iPod connector on one end


(Sorry couldn't resist.)

It pulls the wires from several of the pins in 2 of the plugs in back. I'll get you the exact pinout and a picture, in a day or two. (Need to find my camera)
