Hi all, Basically i'm wanting to add a USB for charging my phone in the armrest. I've found a 12v to 5v step down converter on ebay and a USB to extension so they can be wired together. What I need is a live. I was going to use the Cig port but i've found that it is a constant live (Correct me if i'm wrong), even when the ignition is off and the car is locked. I don't want the give the step down converter constant live when i'm not in the car to stop it getting too hot and going wrong. (I don't leave the cig to usb thing I have in the cig port all the time as it gets hot) Now the next place I though of was the concert II+ as hopefully it'll have a switched live going to it? It's no problem getting the leads to the back of the stereo as i'll be having to pull the Aux lead through from there too (still looking for someone to code that in around Cardiff ) So does anyone know which cable will be switched live on the concert? I can see the ground wire.. Thanks!
