so...in my dd i have a decent pioneer headunit but my problem is theres no aux input to hook my zune up to. i dont want to go blow 100-200$ on a new headunit just to get the aux input so i was wondering...if i just bought a newer pionner faceplate should it fit my cd player and would the aux work, instead of buying a whole new headunit?

 

No.

What unit do you have right now?

If it has a P-BUS or IP-BUS in the back of the unit (blue input), this can be hacked for Ipod w/charging capability.

Review this site.
