In the iPhone settings there is an option called “Allow CarPlay While Locked”. Make sure it’s enabled. Below the link on how to enable it

I also use the USB in the centre console and have a wire hanging out the side that I plug my iPhone...
Replaced cheap looking console panel on my 2016 GT with a new one with leather and red stitching. It’s an easy one to one replacement. Optically definitively a small upgrade.
Finally got my Zl1 tow hook installed. The installation went well without removing the bumper. As I have a honeycomb mesh grill, I decided to install two washers at the cutout. It protects the grill around the hole and looks nice.
