Hi - I have a 2006 Sequoia limited with the rear entertainment system. With that we also have the nav system screen in the front dash. Two or three times when parked of course, (please don't lecture me regarding this use while driving) we have been able to see what is playing on the rear screen, on the front nav system/radio screen. The trick is that we can't figure out how to make this happen, it's not really something I'm concerned about being able to do, however I'm curious how to make this happen. Can anyone help me with this question?
