I'm writing this DIY because recently I had got into an accident. There are other DIY Dash cam install (I think blackvue that was pretty popular) thats inspiring me to post this.
The dash cam I bought is from Spy Tec from Amazon.com model A118-C.
Here's the link:

Link for A119 (Better option and newer, I think its 20 extra dollars):

When you unpackage everything you want your long 12V charger, mounting clip, and A118-C with memory card inside.
I will show you my method of routing my wire.
1. Determine where you want your dash cam to be installed.
2. Start tucking the wire inwards to the head liner
3. Once you stuffed the wire all the way towards the passenger side, pull out the plastic A-pillar by pinching the top.
4. After the top part of the A-pillar comes off take your finger on to the outside of the exposed A-pillar by pulling out further
5. After the A-pillar is popped out enough, you can start routing the wire towards the side of the dash pillar.
6. Remove the side plastic piece on the dash-pillar by putting your finger in the small gap in the bottom
7. After letting the bottom of the side piece pop out enough you can slowly work your way up to remove the entire piece
8. You want your wire to pass through here so you can plug in the 12V plug behind the glove box
9.This is how my set up looks like
