According to our salesperson, the keyfob with display monitoring unit should cost around $500-$700 when they become available. The installation by the dealer will cost more. The dealer quoted us $2000 for the whole thing. They had to research this for us. What they found was this option was available with the Escalade already. Since they are both GM cars, they can get the equipment from the Cadillac dealer and install it. Too bad we're still waiting for our vehicle.
