[Pacecar]

I got my F11 520d delivered last week. It was ordered with the Hifi system (ie. 12 speakers instead of the standard 6, but not the Hifi pro digi system with 16 speakers).

However, I seriously doubt that my car got that Hifi option actually installed: music (radio, ipod) sounds quite "flat", and not at all as good as when I tried it out in the test car that had the Hifi option; also, I just cannot locate more than 4-5 speakers (2 in each front door + maybe one on top of the dashboard, or is that a vent? -where is n°6?)

So my question(s):

1) Is there an easy way in the car to check?
2) If indeed it was omitted, how do you recommend to proceed? Can I demand that it still be installed? Is this possible without cutting up the interior trim? Will it be the same quality as if it was installed in the factory?

I did not yet call my dealership to complain; I want to be sure first...

Thanks.
