I've got an 2006 RTL with out Nav. Has anyone used the USA-SPEC ipod interface? Hooked one up? Any info on them at all ? Do I even need to buy this part to hookup Ipod ? Here is the link to see it. Its at the top of the page.

Also does anyone have specs on where the sub is ? I know its in the back behind the bench seats, but specs on it ? I might want to put a bigger sub back there. I have been looking for the specs to build a box or to see if it will even fit.

 

It is very small back there. I do not think you could really get anything bigger in it. I had to take one out to install a backup camera and rear bumper parking sensors.
