Thanks for the reply. Interesting to note 10 mpg drop, is that more so on the motorway? I know driving one will be good and want factor will go up so deciding on the finances first beforehand. My CT Advance is a 2014 and has the newer SAT NAV that's in your IS which I use very little for directions and when I do, find its annoying to operate. I agree with you on the posh voice.
