USB PORTS are powered by splicing into the cigarette lighter power and ground wires that are fused.  The ports are 5 volt, 3 amp, 15watt.  The connectors are included along with zip lock ties to secure the usb transformer to a bracket behind the CD storage trays.  The installation takes about a hour and I will include some written instructions.

The cell phone mount you see in the photos is for sale here on bey also.  https://www.ebay.com/itm/126404647248?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=N2XZfSulQ0S&sssrc=2566055&ssuid=N2XZfSulQ0S&widget_ver=artemis&media=COPY
