Looking for some clarity on installing a Alpine CDA-9885. In order to keep the dash controls, do I purchase:

IR DCI for Alpine plus Modifry's stereo adapter
or
IR DCI for Alpine plus Modifry's PnP adapter
or
Wired DCI for Alpine plus Modifry's stereo adapter
or
Wired DCI for alpine plus Modifry's PnP adapter

Also installing an amp to drive new door component speakers (Polk db6500)
I also want to utilize the new head unit with my Ipod, I allready have the KCE-422i Ipod control 1.

I do have the detailed thread on a complete stereo upgrade...HU, amp, speakers..etc. just need clarity on the dash control interface.

Thanks in advance

 

Wired DCI with either depending on how easy you want it to be, the PnP harness will be easiest, the normal harness requires you to splice/solder wires.

 

Thanks
