Exterior Rearview Mirror problems of the 2004 Chevrolet Suburban

I have just purchased a 2004 k2500 chev. Suburban with the electric camper mirror option. I have driven it two weeks and discovered that the passenger (convex) mirror has a huge blind spot that hides all cars and up to medium size trucks. It is dangerous. The dealer has inspected the truck and confirmed the problem. The service manager has contacted Chevrolet and they say there is no fix. I contacted Chevrolet and they confirmed there is not fix and also confirmed that the service mananger has recommended that this be corrected. Chevrolet's position is that they are going to do nothing else.
