The Sat nav is different from country to country...here in japan we have some of the best in touch screens, which is what is in this model. But there were more than several choices from which to make and I chose the 2nd tear from the top shelf choice.
Again post code recognition, Japanese sat navs are perhaps higher in function that what you chaps are offered there with some very high specs.
Most of the Breras or other cars of any make sold here have some pretty high functional Sat navs, check the internet on that one...too many choices here.
The brera here has standard rear parking Sensors which are not an option as they all come with this and of course I have also been given the rear camera as a freebee, although it is not the high spec version but I do not really need it unless with high curbs. We have alot of those damn things.
At the end of the day...I am not sure where you are getting your info from but it seems a bit wrong. Are you only thinking of UK versions...?
