If you purchase a Sync Lockpic from Coastal Electronics, which just plugs into the exsisting wiring harness, it takes away all the nanny controls and lets you do address input,watch dvds and other things that are disabled while on the fly. It also lets you incorporate a camera into the system that turns on in reverse or you can turn it on whenever you want. Not to mention the 10 gig hard drive that you can store music on adn all of this is voice command through Sync.
