I've spent hours looking at wiring diagrams to see if there's a switched circuit back in the rear of the X, that I could use, by hijacking it for the rear camera, instead of the intended OEM usage.
Since one of the PO's took away the CD changer, and made a mess of all the wiring in the rear, I can't tie into the CD changer circuit, because I can't make heads or tails from the rewired mess (it's also the reason I haven't installed an Android radio, and still use my tablet and the cheapo radio in the dash).
So, in lieu of making a bigger mess, my "quick fix" two-button push camera's activation method seems to be the safest, easiest way to use/test the $35 dash cam.
I spent another $9 for the extension cable, so my project cost is roughly $44.
If I eventually find an intact rear seat wiring harness back there, I'll get the button module that activates the circuit (but not the relay, because I don't need the power from pin 30, just the control power). Adding a switch/module off of eBay (about $50) or from FCPEuro (about $105, if I get a tax refund for a change), just makes the project more costly. But then, I can install the switch/module in the backside of the console, so I can reach back there and turn on the rear camera from my seat. Not much of a difference.
Seems like a lot more expense and work, just to clean up my "quick fix" wiring.
