Finished my OWL Media Mount install last night.
Here are some pics documenting the install on a 2006 LC with NAV. I took the pictures while I was re-installing it so ignore any continuity errors with fasteners.
Remove the side vents, I used the trim tools from harbor freight to get them started, then they just pull straight out. You can remove the 2 connectors to get them out of the way, or just let them hang out.
Next unscrew the 4 bolts holding in the entire unit.
At this point I disconnected all the plugs and took the whole unit to the bench. It seems like a lot to pull out, but don't worry, the plugs are all unique and they can only go back one way.
Once at the bench I first used an 8mm wrench to break the bolts loose then finished them off with a screw driver.
There are 4 bolts that hold the tape deck in it's chassis, similar to a hard drive on a computer, they are the black ones.
There are 4 screws that hold the face plate to the fascia, remove them. On assembly be careful to not over torque, it's just plastic in there. I gave one an extra little twist and had it pop on me.
There are two bolts that hold the lower chassis to the lowest row of buttons. These sandwich the entire assembly. Take these out.
