Aha! I didn't know that. Of course, as it turned out, I didn't plan to buy a tuner module for boat or car (I decided on a side-by-side install in both cases with a traditional single DIN receiver) or for home, but what you are saying is that any sled with a tuner module attached will allow the Empeg to store a unique profile distinct from other plugged-in-sled profiles?

Hmmm. wonder if there's any way to fool the Empeg through the tuner module plug short of buying 3 tuner modules?
