I wanted to darken the silver trim around the outer air vents since the reflection on the window (seen in the side view mirrors) was distracting. Tint may help but I wanted to test out vinyl.
I removed both the driver side and passenger side wood trim panels to work on this indoors.
To remove the passenger side, you must remove the center radio bezel to access the screw. Lift up the cubby door, grab above it and pull. I only had 1 wire clip going to the radio which I removed. Then remove the 7mm screw holding the wood trim. This too is held in by clips. Work your way down and it pops off. Here's where I failed. The vent stays attached. There are side clamps on the vent body that you pinch in while pulling out the entire piece (wood trim and vent as 1 piece). I broke 2 clips used to attach the vent to the wood trim because I took the wood trim only.
Mind your clips because sometimes they don't all stay attached.
KEEP VENTS ATTACHED TO AVOID ABOVE!
The drivers side required a little more work. I removed the small panel on left side of the dash. I then removed the ring around the steering wheel attached to the leather surround. All standard clips. Then I could unclip the top portion of the panel below the steering wheel. Only the top 2 clips. This gave me access to the screw - 7mm. Then pop off the wood trim again keeping the vent attached.
Then I wrapped both vents in 3m matte black and reinstalled. This was my first time using vinyl. I think it came out pretty good. Take your time. Heat is your friend. The vinyl is very forgiving but don't overstretch. Leave enough vinyl for all of your sides.
I did leave the little inner chrome trim as is because I thought it looked cool. As I suspected, I do get some reflection from this but its much, much better than before.
