Ali express have a replacement rear vent with two USB ports for charging.
It cost me around £60 inc delivery.
My first experience with Ali express involved a Dynaudio Retrofit kit which was a complete disaster,I said I would never buy or even try to buy as the above turned out from them again.
I was also looking at retro fitting wireless charging,but gave up due to lack of info and costs of the parts I could find.
This is when I stumbled across the rear replacement vent on a another forum and watched a how to fit video on YouTube.
Decided to give Ali express another chance,but i wasn’t expecting much.
The part arrived and was spot on-I’m a stickler for only putting genuine parts on my cars and if this vent is a fake,it’s a very convincing one-it’s all stamped up and the texture,colour and fitting matches perfectly,side by side I could not tell the difference.
Really easy to install,it’s powered from the 12 volt port on the centre console,just plug in and play or charge in this case.
