I have a z1 in my 2006 Ford F150 and a z2 in my 2007 cadillac CTS-V. In my truck, the nav arrow always poins up and the map rotates so that the arrow alwasy poins up in the direction that i am driving. In my car with the Z2, the arrow points sideways or at an angle all of the time. I cannot get it to point up. I have tied switching the position in the menu and hitting the "north" arrow and these do not help.
Any help will be greatly appreciated as this drives me crazy!
