surround sound...plannin my ice set up for my upcoming beast

 

I may be mistaken, I think it is actually 7.1

yes it is 7.1

is this standard even without the nav option?

 

Looks like it, it is listed in the audio section of the features. You got a 55 on order?

 

have one coming 1st week of Nov...options i got were pano roof, keyless go, lighting package and parktronic...didn't get the nav opt as i heard that it sucked, just stuck at this 7.1....hopefully i can confirm that this is standard on the car with the stock radio

 

Still its not as good as aftermarket but its half way decent and better the most. The more speakers doesnt mean the better in audio play back.
