Hi all,
I've been testing out my new install today.. everything appears to be fine until I plug my laptop (the carpc) into the car charger - (A cigarette lighter socket one, that puts out 19v to charge the laptop)
As soon as the laptop is plugged into the power adaptor I get noise from the speakers in the car!

I had the same problem in my old car with a similar setup, so I'm interested to hear how everyone with laptops powers theirs or what I can do to stop the noise - its really bad, I haven't tried yet.. but I don't think a ground loop isolator will cut it
Any thoughts appreciated!
