Just a heads up for those that are looking for a wireless CarPlay solution, I just received my CarPlay2Air unit (carplay2air.com). Bottom line is that it works well in the ST, but didn’t work correctly out of the box. It kept attempting to make an initial connection, never displayed anything cleanly on the screen (a bunch of artifacting and gibberish), then disconnected. I was getting ready to pack it back up and ask for a refund, but gave the software update process a shot, and it worked!
If anyone else purchases the CarPlay2Air, just know that you’ll need to follow the instructions for upgrading to get it to work correctly. One last thing, I emailed them before I purchased to ask about any discounts, and the guy sent me back 10% off - use code 10NOW when you checkout.
