I bought my 2012 Exl (no res or navi) 8 days ago. Traded in a 2009 Sienna. The Honda is much nicer. At first I thought there was no compass in these cars but my best friend just bought an identical Exl today and his has a compass function which displays the heading with a red arrow in the upper left corner of the big color screen. How do I turn this function on in my van?
