Decided to replace the stereo on our boat and the remote it came with was IR, which is entirely inadequate IMHO. Maine Sail mentioned iJet in a thread back in '07.
Post #6 Great Cheap Marine Stereo (Pick Two)
I have a similar RF setup for my home stereo except that it has a small LCD screen on the remote.
I find it convenient to have a screen on the remote for when we can't remember an artist or song name. Found one similar to what Maine Sail suggested, but it now has a screen.
I could only find it at one website ($35). I ordered it on Tuesday and it showed up today (standard shipping was $1.99).

Hooked it up and it works great, just like the DLO remote I have at home. There's a AAA battery for the remote, and the transmitter runs off the iPod (it's a pass through connection on the transmitter too)
I didn't see it when I ordered mine, but if you spend $40 with these guys, they'll throw in the remote Maine Sail mentioned for free. Also, I got a coupon in the mail with mine for $5 off if anyone wants to use it (it says to share with friends, so I'm not breaking any rules). The code is Order5Off and it's good through the end of this year.

I have no affiliation with Apple, Bill Gates, DLO, iJet, valueoutfitters or Maine Sail (other than hero warship)... I just like a nice audio setup and wanted to pass it along.
Once again, thanks MS
