I have the upper Nav trim available for sale. This includes the main trim piece, air vents and duct, Garmin GPS unit, power cord and the adapter to make it plug and play in the car.
The trim piece at the bottom has a chip in the paint, it doesn't stand out too bad, it's been there since I bought the car 3+ years ago.
The opening is 4 x 2 1/4 if you're looking to mount something else in there.
You'd need to acquire the radio surround and console piece (and I believe the cigarette lighter cubby) to complete this kit, there's a couple sellers down under that could get it for you.
Asking $250 shipped to the lower 48.
