+1 on the HK stereo! Well worth the money and adds value to the car as its now back to being branded as HK.
I couldn't live without heated seats and a heated front screen (but that's a big debate among owners!)
I also use the auto lights and auto diming rear view mirror - all in the Vis pack I think.
I also selected the Visual Boost Display (AKA Telly) and the rear parking sensors. This gives you the parking radar on the big display. It also allows full iphone integration with playlist selection and shows your album art on the 5" screen (very cool feature).
I also use bluetooth a lot but think this is standard now?
As is DAB.
Oh one last one, centre armrest! I tried to stop using it (folded it away) to see if I could - I couldn't!
Panoramic roof is nice but a bit pricey perhaps?
Mini connected (iphone app) is toot - IMHO! used it a couple of times but no more as its a pain to set up each time you want to use it.
Happy speccing!!!
