I've tried to use 12 volt socket in my A1 Sportback 2012 and I found that none of my 12 volt adapters are working. I have a standard adapter that was working fine in other cars, but not in A1. The lighting is working fine, but what kind of adapter do you suggest me to use ? The connections inside the socket are quite different from any other I have ever seen so far, yet in the car's manual it is written that it is possible to use GM Tech 2 for up to 100 watt. Please advise what company manufactures and sells appropriate 12 volt adapters that will fit into A1 lighting socket.

Thank you in advance,
