80's Metra GM Kit and bluetooth update?
I am having trouble getting my Metra kit to mount my headunits, there doesn't seem to be a way to lock the sleeve into the headunit let alone into the single din adapter that Metra makes.  Metra makes it as a large customizable kit but doesn't seem like anything works for it.  This is that kit for reference.

My second question is for my second headunit for the car, I bought one specifically to run my air ride and backup camera.  There was talk on the Facebook page of an update coming that would allow me to be able to pair it and run the app to control it.  I bought the second unit so that there wouldn't be any other issues with bluetooth needing to connect other devices like my phone to interfere.  Here is a link to my old Facebook original  post
