Yep. In fact if you look at the 4th picture rob put up, it is not a Camelot, but one of our production navigation radios. Nice screen, lots of buttons, made it a perfect candidate to demo the capabilities of the hardware behind it. That particular version didn't have a tuner, so we had a lot of buttons that were no longer relevant. Looking at the photos, the one actually on show didn't have all the buttons relabelled (good to see my stick-on labels lasted the show!) - there were some other shortcuts, but they would be changed from what we know now.
This drops straight into a Ford (obviously my own Focus being able to take it had no impact on the choice of donor radio!), but any other OEM customer would be able to decide buttons, displays etc.
We do have an aftermarket division as well though.
I'm not entirely sure what a Chevy Tahoe is, but I'm guessing it's not pretty!
