infrared remote
What make and model of head unit? If it originally came with an IR remote then the SWI-X is one way to go. But you'll need the original IR remote to program the SWI-X. If it's a recent model that supports wired remote control then you can get the appropriate adapter based on the head unit brand (SWI-PS for Pioneer and Sony, SWI-JACK for JVC, Alpine, Clarion, and Kenwood) and you won't need to use IR at all.
