I have an FRD1 from PAC Audio that allows for the back up camera or game system/dvd player to be hooked up to the factory screen in the Navigator and Lincoln LS's with the factory Nav. Bid on it if you have ebay or make me an offer! item http://cgi.ebay.com/ws/eBayISAPI.dl...MESE:IT&viewitem=&item=140108720067&rd=1&rd=1
