So I took the day off today to go and pick up my black Golf GTI DSG optioned with ACC, RNS510, Sunroof, Roof Bar Set with 2 Bicycle Holders. When I was given a tour of the car I commented that it had 18" Detroits instead of the 17" Denvers—I'm going through novated lease and basically chose a car that was offered with the above options even though I had not planned on getting a sunroof.

The fleet rep said he would check the paperwork since he remembered that the car was offered as is. He then comes back to inform me that the Detroits were meant for another black GTI and that the RNS510 for my car had been installed in the other GTI instead. Naturally I wasn't happy since I would have to wait until next Tuesday or Wednesday to pick up the car.

This brings me to a question: Isn't the RNS510 a factory option? I had been under the impression that the all the options I had were factory options (naively thinking that the Detroits were also factory options) so I didn't bother to change anything. Now I'm reading that there should be an antennae for the sat nav since it is a factory option but you can also get is as aftermarket. Should I be worried/pissed off?

Would really appreciate any advice from you guys. Thanks in advance.
