I just did it. Here's the simple low down.
Slide in a butter knife or non-marring thin plastic tool (cheap on Amazon) with indents on the inner side of the map light lens in the middle front area.
Front part of the lens is where it snaps in vs the rear part which slides in with a tip that you don't want to have damaged.
From there, use the indent on the non-marring tool to pull out the lens. It should snap out of the front snap in. After that you can pull it out with hand.
For the back piece, you can see and indent on the front portion. Cover a medium flat head screw driver with thick tape to prevent marring the plastic surround and then pop out the lens. The back of the dome lens is where it slides in so don't damage the three slide in prongs.
Here is the JDM Astar LED in the front map lights vs the OE bulbs. No resistors needed. They are much brighter than most off the shelf LED lights that cost more. Ask me how I found out.
I also have the same LED bulb in the hatch cargo light. My wife complained that it was so bright in her eyes so I made it face a bit downward to the cargo floor and that fixed the issue.

Here is the same bulb installed on the dome light.
It is 31 mm vs 30 mm on OE bulbs, so you will have to bend the hard tab just a bit to mount the bulb without bending the soft tab too much.
