I got it from AliExpress.

I left my review with that seller. There a few on AliExpress to pick from. The fit wasn't perfect. The pegs and notches were slightly off. If they matched my Golf, the unit would fit. The power source came from the front cigarette. The unit came with a harness which would piggyback off the front cigarette lighter socket and to the unit itself. You will definitely have to remove the center console which was a pain to remove. Overall, my wife appreciates it since she can charge her phone in the back as she sits with my 18 month daughter. If it weren't for her, I'd say this modification isn't worth it.
As for the front, I have seen people remove the front cigarette lighter socket and replaced it with USB ports. Not sure if anyone has done anything USB C related. Anything is possible though with money and time. Would be a fun project to pursue.
