If I were to buy a touchscreen to replace my radio, how would I enable it to also have iPod capabilities? Is there something I have to buy to put in the punchout under the air controls and hook it up to the touchscreen unit? Any links or anything would be helpful, thanks.

 

you should really do more research

a "touchscreen" is simply a monitor that works as an input/comtrol device

unless you buy a Navi that has a touchscreen
is that what u meant??
as for the AUX input
the IampopularPod simply needs a male/male mini-jack cable to plug into the AUX input of the radio
the radio has to come with an AUX input
