I can vouch for namegoeshere that his DIY guide to add a Blitzsafe HON/AUX DMX V.2X works for the Navi in a '06 sedan. It works really well, so thanks for the guide.
The installation is a little different since the plugs are placed differently on the back side of the Nav unit. You have to unscrew the whole unit from the chassis to get access to the plugs namegoeshere describes in the guide.
Let me know if you have any questions and i can give some advice installing it.
I actually have an extra Blitzsafe HON/AUX DMX V.2X unit that I could sell you, too, if you're interested.
