To answer the OP’s question:
I tried a few of the CarPlay options (OTTOCAST Wireless CarPlay and CPLAY2Air) plugged into the center consul hidden away as described. They are not super small like a mouse dongle but you won’t see them. I did have some connectivity issues with both. Nothing bad, just needed to be unplugged and then plugged back in. To be clear, these dongles are defiantly NOT supported by Apple so they use “work arounds” (hacks) to connect to the UConnect4 which can result in a less than ideal user experience.
I have taken apart the dash and you can definitely run a wire up there behind the dash but your going to have to drill a hole in the dash somewhere. Personally I don’t love the look of cords. But it has been done.
But the real issue with CarPlay was when navigating using Google or Apple Maps. When you’re connected to CarPlay the moving map is disabled on your phone. All you get a list of turn by turn directions. I really like manipulating the map when navigating on my phone. So CarPlay wasn’t going to work for me.

That left me with no option but to use the built in Bluetooth in the UConnect4.
My experience using the UConnect4 Bluetooth has been superb! I haven’t missed Apple CarPlay at all. It is seamless, IMHO. Never drops a call, never had an issue with music, connects automatically and even auto plays music where I left off. Basically Apple CarPlay but with full Map control and no annoying dongle that needs to be reset.
I have it setup on my “Media” with SiriusXM, Bluetooth, and FM as the sources. My daughter and her friends often want to play their “cool” music
from the back seat. It’s so easy to change the Bluetooth source in the “Setup” and select her phone. I love the UConnect4 and the Bluetooth which is very stable. It does everything I need without all the frills. Kinda like my Jeep 392.
