Thanks, that really suck, . I do not want to spend $200 plus.Back to the drawing board,lol.2004-2007 is completely different than the 2008+ models. To make the '07 and older work you need a AV box such as a unit from TV&NAV2Go. You connect this to the DVD based Nav drive, and you are then able to run an AV cable from the new box to your DVD player. It is a little time consuming, and you have to make sure you are tapping into the correct wires, but it works. Also more expensive because you have to purchase the box.
I'm in the middle of trying to get this done now...
the 2010 qx is the same as the armada in terms of that so yes the mod will work there.
all you need to do is verify the VSS and parking brake wires on the Q and you are set.
