Finished the front dashcam install! Still planning on doing the rear but am going to see how the Garmin dashcam mini does before ordering a second.
Step 1: Trim Removal
This is the only piece necessary to remove and is super easy. It's held on by 3 metal clips and a tab in a hole at the bottom edge. Just pull it away from the dash, then slide it upwards a bit to get the tab out of the hole at the bottom.
Tab on the right. There's also a little edge that tucks behind the trim piece below it.
Step 2: Running the Wire
The "hardest" part is fishing the wire from next to the glovebox through the gap between the window and A-pillar trim. I used a piece of solid wire to go from the window to next to the glovebox then taped the power cable to it to pull back through. There's plenty of space between the dash/A-pillar trim and the windshield.
The wire can then tuck between the windshield and the rest of the trim super easily
Step 3: Power Source
I used fuse F53 just like everyone else has.
The fuse tap didn't seem to go in all the way so I chopped it up, removing the unnecessary lower fuse slot. I used the scraps I chopped off with a plastic welder (basically a funky shaped soldering iron) to close off the holes. Probably not necessary but only took a couple of minutes.
For the rear camera I'm planning to tap off the existing circuit for the 12V outlet. It'll probably require a bit more trim removal but hopefully will be close to as easy as the front was!
