Personally, I would take of picture of the unit and make a proposal to your dealer... you'll trade out the radio at your own expense in exchange for a store credit, merchandise, or services.
Let's face it.. they don't want the hassle.. you don't want the hassle and have your rig sitting around at the dealers for how long?... just to get a slightly better sound system. You can get a FAR better sound system with all the features you want for much less than what FR or your dealer have to offer... without all the hassle.
It's a tactic I've used successfully before. Ie., You folks dropped the ball on "this"... instead of all the hassle how about you give me a couple maxair II vent covers, top off my propane tank and we'll call it even. ;-)
