I have the idea (cannot test yet, because I'm at work) that I tried it like that. I tried to connect already so many times..... I will definately try it like this tonight. Is there a possibility it might have something to do with the extension cable? mini usb - female usb from the set and then male - male to laptop?

In other words; does it make sense to retrieve the set from the dashboard and connect directly with a mini usb - usb (cable from a samsung smartphone for example?)
