Just installed the new PDIM in my 2011 Equinox 1LT and it was as easy as listed here and much easier than I expected.
Thanks for the posts.
The trick about going to AUX and hitting MENU is money. Without that, it just looks and functions the same. I don't know if you have to hold them down or press them simultaneously (I tried both) until you a display asks if you want to pair a bluetooth streaming device.
So simple and worth every penny for my 1hr daily one-way commute. Many thanks!
