Buy a dension ipod controller. just google dension clio ipod. Sorted.
I have one and it controls the ipod on tunerlist stereos with the stork controls.
Only catch i you cant use cd changer as you need to attach the dension unit to the cd input on the back of the stereo.
But if you have 40,000 songs on a 160gb ipood, then why do you need that and a changer.
Best add on i ever bought ftw!!
