I would suggest that you contact Toyota Customer Care and open a case with them (save the case # they give you). They should be able to help mediate this concern with the Dealer. What it is you want, is a Repair Order to be opened on your 2004 4Runner showing that your vehicle qualifies for this warranty extension and that a dash was ordered for you. This way it is in writing and not just verbal. I'm not sure why you Dealer is acting this way as it is a very simple process. I hope this helps you and please let us know how it goes.
