Hello Community.

In January I will buy a SL R230. Now I'm driving a SLK with a 'Roof Modul' from www.xcar-style.de (Sorry, I don't know the english word for it. Can you tell me the correct, please?)
For my new SL i will buy such a Roof Modul, too. I will buy it from XCar-Style, too. I think the service is verry good.
And here is my question. Has anybody bought and installed such a module before? They say installing is easy to do up to 30 minutes.
I hope, you can help me and give me some help.

Thanks and Best Regards Philly (Germany)
