Just got my Xoom and 2 OEM docks. 1 dock is for home, and the other is as you guessed it...... for my custom integration to the dash. I am taking my OEM navi hood out, and getting the plain hood and customizing it to integrate the Xoom I just got. I'll post pics on it as soon as I start the project. Still waiting on the new dash piece and then the dream comes true!

 

trade you the navi hood for a plain one. LOL. I look forward to seeing this, I had the same thought myself (though with something cheaper than a xoom).
