I too have like 5 of those chargers that are now useless cause the wife's car being a 2015 already has them built in from the factory lol. I love the flush design. but now as you know i modified my factory outlet. it is only 2 wires to hook up but it's also a way to make our nbs's feel more modern and convienent. your nnbs is already modern so a mod like that really isn't necessary.
That being said isn't there a straight 12v usb option for the nnbs's for a factory look and install. one that's not hooked up to the infotainment system?
Just a thought for the future. I know it's hard to work on it being the wife's daily.
