OK - so your unit truly is not capable, but the brochure specifically says "ipod dock"?
When we were looking we found several times that the brochure, or more likely the large carboard dealer promotional signs in a trailer did not match the features. For example, one stated "upgraded Serta perfect sleeper" when it had a generic no name bed. Many had the advertised touchscreen stereo replaced with non-touch units and no remote.
We were told frequently that the manufacturer does not guarantee either the brochure or promotional material for accuracy. In some cases they have a problem with the unit or device (the touchscreens were apparently all crap) or they simply make a change mid-way through production. And then most dealers order units "their way" which don't match anything.
So while I encourage you to raise all h-e-double hockey sticks with the dealer, I will be shocked if you get any resolution. Which sucks.
