What is this on E450 Ford dashboard?

[GaryKowal1]

I asked at three different salesman at the RV dealerships what this rectangular area was with a button? On it. No one seems to know. What is it?

New or used vehicle? It looks like something a PO added. Is the display above it (clock or maybe thermometer) stock?

[GaryKowal1]

Every Winnebago that I've seen has the same square area with a button on it. I added the clock. It's a Ford part 4 something

It is an OEM (Ford) aux input for factory radio. It isn't used by any RV upfitters so they pop a cap plug in it.
At one time you could "port" an iPhone to the aux but iPhone changed the interface of their phones too many times over a few years therefore aftermarket gave up on supporting the Apple.

Ah, shootskis. I forgot all about that. A year ago we rented a 30' CruiseAmerica Class C that had one of those. It worked. It was a stereo headphone jack style connection. We took along an eighth inch patch cable and successfully streamed audio from my phone through it.

Mystery solved. Thanks! Bkg!

The last one I saw a couple of years back when I had a class C was to resent your low tire light. If you didn't have that option--it did nothoing.
