I recently purchased a Pioneer head unit because I know they have some that are made to work with their boat remote (wired remote that is water-proof). Guess what I discovered? The Pioneer remote acts just like the Sony RM-X4S remote. Well, very nearly the same, but knowing how the "internals" operate I figured it was close enough.

So I did a test with the Pioneer DEH-P3700MP and my standard Sony Wired DCI - Works perfect!

Next step is to buy a JVC and see how it works. I already know the Alpine wired remote is totally different so Ive got another project in the works to figure that one out.

Here's a list of Pioneer head units that are compatible:
