I have a last off the line 2019 F31 335xd MSport with SatNav Pro installed with NBT_Q firmware (With CarPlay activated from the factory).
I wanted full-screen carplay with IOS13.1 after a bit of research I am pleased to say it works with no issues, this what I needed to do:

1. Bought a ENET cable - £8 Ebay
2. Purchased this fsc.carplay - Around £22
3. Sent them my VIN and a photo of the SatNav Firmware version (mine is showing NBT_Q so the ENET cable is required) - To get this info goto: Navigation -> Settings -> Position And Version -> Version Information
4. On a Windows laptop download the software and activate it using the code sent by fsc.carplay
5. Plugged the ENET cable into the ethernet port on the laptop with the other end in the OBD port and ran the software as per their instructions (engine on, strong wifi connection required)
6. Sat worried for 6 minutes and watched the SatNav being patched.
7. All done
8. In Connected Drive - goto options and select 'Update Connected Drive Services'

Note that split screen is not possible after the patching and if the FW every gets updated by a main stealer, the patch will need to be reapplied but the purchase is lifetime and comes with free updates ETC.

CarPlay is so, so much better in fullscreen
