Tidied rear armrest wiring and put all trim back into place.
Tested USB C adapter with iPhone 16 which is USB C. Charging came up straight away . Phone also came up as USB entry on snapin adapter. Turned off CarPlay and tested , USB audio and Spotify app via USB c adapter , all working correctly. Charging is faster too via USB c adapter. 15 watts so more useful.
So now I can run my 256gig thumb drive with quite a few lossless encoded albums off the usb b , Anything lossless audio wise on the iPhone can be played via usb c, handy for Apple Music lossless. Otherwise wifi CarPlay for anything else.
