I bought the mygig unlock from tvandnav2go for $194.
I bought the monitor below for $46:
I was skeptical about the quality of monitor, but I have at least 2 other things I could use it for, so I decided to roll the dice. The quality turned out pretty good. The audio picks up some noise. The blacks aren't very black. But both of those are to be expected from cheap Hong Kong stuff, and overall it was quite nice. I would have been happier with a 9", but I guess that's always the case
The mygig unlock install was a little tricky. First of all, the trim piece does not come off as cleanly as I would have liked. I bought the harbor freight plastic tools, which I highly recommend. I also took my time. Even so, still two of the little orange clips popped off, which I believe is unavoidable. I could only find one of them even after searching for at least 30 minutes, and even sucking around with a tube collected to a vacuum cleaner. You can't buy the clips individually. They only come with the entire bezel assembly. I have to figure most people just don't let it bother them.
Also there is no place to secure the unit. I fed the wires to the open cavity behind the HVAC controls, but struggled to find a good point to secure the unit. I ended up zip-tying it to the keyless antenna. You must secure it to something, or it will find a way to rattle.
Running the video wires back to the console was very easy. Removing the console and gear shift trim was much easier than removing the bezel around the radio. I ran them back to the armrest compartment and drilled a hole for the single DIN jack for the tv monitor. The jack is facing downwards, so you wouldn't even know it is in the armrest compartment if you weren't feeling for it. It's nice there is the little notch for running wires out of the armrest compartment. One of the several things that made this a clean-enough-install for me to do on brand new 40k vehicle.
The TV monitor came with a little stand with padding mounting tape. I bent the stand around a 4" piece of PVC that matched the contour of the center console. I "unstickied" the tape by putting a bunch of lint on it, but it still has grip. Then I strapped it down with an old ipod armband. It's not going anywhere.
The mygig unlock is wonderful. "View Video" button is always visible. Before it was inconsistently visible even when stopped. Navigation works great. The backup camera is always available. It's quite a fun novelty when driving 85 mph, but it's really useful when pulling into my garage to make sure I'm in far enough. The VES inputs and outputs are a really nice bonus.
The 430N control is pretty slick. It let's you send any of the inputs to the front or to the back.
Also you'll see a picture of a brace I used for gluing down some of the wood trim. Discussed here:
How is the interior wood trim affixed?
