U have to get video in motion, or vehicle in motion activated thru vcds vag com etc then make sure u have the correct cable for videos. Then it should work fine I think
I'm afraid it's a trip to the dealer then.. Seen on an audi forum in Romania a guy claims to be able to activate ur sat nav thru the 2 sd slots.. His names Benyclaudiu, he seems to know wot he's talking about tho n quite a few folk have used his services so mite b worth calling him. His fone number is on there
