This morning, I was ready to buy a DVD ver 07.1 update for the SC and made some quick phone calls to local dealerships. At Longo Lexus in El Monte, the phone quote given was for $350. Just 500 feet away is the Longo Toyota parts department. I got a quote for $250. Near my work is Toyota of Anaheim in Orange County. They quoted me $400. When calling your Toyota dealer, make sure that you state the Toyota model that shares the same DVD update disc as your Lexus model.
