I have everything else connected but the original usb doesn’t connect to the uconnect5 port, so I have the conversion cable shown in the pic with the brown plug on one end and black and gray on the other. I can seem to find a way to access the back of the media hub which apparently is where the black and gray plug in to. Also, wondering even though the media hub isn’t plugged in why Apple car play won’t work via Bluetooth since it’s supposed to be able to with uconnect5? Thanks!
