Update on my post
#15 above.
The Kenwood unit I mentioned we installed in the Mustang lasted less than two weeks. It developed an issue where anytime it did something on Bluetooth it played at just past volume redline. I thought it was going to blow out the speakers. Crutchfield worked with me for about an hour trying to adjust it, but nothing we did would fix it. It was also happening with multiple phones.
We RMAed the radio and they shipped me the current year model
Kenwood MDX9707S for basically the same price. Took about an hour to swap it out, most of that time was disassembling and reassembling the interior. In the Mustang you have to remove the top half of the console and a couple of dash panels to get to the radio. So far, working like a champ.
I also discovered the Pioneer in our Suburban DOES do AA/CP but it only works wired. The USB cables I had installed 5 years ago (replacing one of the two power ports (OK, Cigarette lighters) in the front console were not up to spec for AA. I ordered a douple USB port cable from Crutchfield that was AA certified, one set for the Mustang and one for the Suburban.
20 minutes of work to pull out the Pioneer, and replace the cable, and now I have AA (wired) in the Suburban. I then purchased this
Android Auto Wireless adapter that allows use of AA wirelessly on a headunit that only does wired. Both units work great.
Honestly, not sure how often I'll use the wireless adapter, likely just on short trips around home. AA sucks the life out of your battery wirelessly so anything with any distance you'd want to charge anyway. The adapter does have a passthrough power charger but I'm not really sure what that buys you if you have to plug in anway.
