Hello I have ordered for my Volvo the:https://www.amazon.de/…/B07C7R5TT1 adapter. This comes behind the changer and has to be supplied seperately with 12v. And this is my problem now. Where can I turn 12v off properly? The cable from the cigarette lighter at the front in the center console is unfortunately so short that I can’t make a bad noise. It doesn’t even stand out of the console. Is there a switched 12v cable on the green plug? äne for the V50? Demand: Can I put the car on ignition to measure even though the plugs are removed from the display and waterfall? Have a bit of a bammel. Or doesn’t the electronics like it?
