I've actually since shorted the data pins and it still showed as charging USB but I was using a crappy £1.30 cable from eBay. However as a last go I tried the official HTC cable from my wall charger and BANG... Straight to charging AC!!!
So I'm not sure if shorting the data pins was necessary but definitely a combo of that and HTC cable no allows me to increase charge while navigating with Copilot and listening to music through Spotify(Streaming and Offline) and also I have a nice usb charger that permanently sits in my 12V socket.
