I very much doubt you'll have tweeters in the back, never known a car to have that, my guess would be:
2 tweeters in front doors 2 speakers in doors 2 speakers in rear quarter panels 2 speakers either side of parcel shelf
Spoke to the dealer today he said that he checked thier demonstrator and it only has 6 speakers and 1 USB and it has the SatNav upgrade ummm guess I will just have to wait to see what mine has when it is delivered
