Front dashcam finally installed. Here's what I ended up doing:
My ICE that got traded for the X had a nifty dashcam that was an overlay covering the rear-view mirror, similar to this:

I like this design as it's hardly noticeable and gives you a bigger mirror on top of all the cam functions. The stock X mirror is tiny and the larger one affords me a better view of what the kids are up to in the back without having to contort myself while driving.
Today I finally wired it up in the X. Most relevant detail I wanted to share is how I ran power from the 12v cigarette lighter socket in the front console to the windshield. I ended up tucking the cable between carpet and the bottom lip of the console, then under the steering wheel paneling and around the main dash (fully tucked into gaps/seams) so that there is only 1 visible piece of wire when the console lid is closed - and this wire is deep between the driver seat and the console - so completely out of the way and fairly stealthy. Since I usually have my phone charger wires sticking out the gap between the lid and console while keeping said lid closed - and leave them tucked between passenger seat and console fir easy access, this does not bother me at all - just a another 2-3 inch section of black USB wire that you can't even see, unless you are really looking for it.
Best part - no messing with splicing into factory wire harnesses / fuse boxes, no bulky OBDII power adapters etc.
Wanted to share the approach with the community. Let me know if there are questions or wanna see pics.
Still picking out a separate rear cam, but have some wiring ideas already - using the cigarette 12v socket in the trunk
