Boy I like that selfie stick sacrifice idea. I'm using a suction cup mount high on my windshield next to my rearview. I would like a sturdier mount and that idea is a good start. Saw a large selling display of those at Home Depot last weekend, I noted they were inexpensive but had no use for it as a 'selfie stick'.
... a sturdy tube extension out the side of my upper console, maybe even clamped in place by that console or thru it.... ... some bolt hardware thru the tube to replace the 'stick' portion...
Been working towards cracking that open anyway, to wire a power outlet where my OnStar microphone was on that upper console, and to provide a short power run to my phone and to a planned dashcam. instead of having a long USB cable trailing up from the middle of my dash.
hmm...
