The latest model
I'm waiting for the new model due next month so only know what I've been reading on various forums.
Only two real negatives so far, no post codes which you did get with the old TT system, although I'm told you can enter the post code on the entry box for a city, I don't know if that works though.
Second thing is no sat nav speed on the screen, something I use all the time to set CC up on my present car.
There's lots of info on utube, its the same system as the Mazda 3.
Also this link will put you onto more info.

Don't be put of with 19" wheels according to the chap I bought a set of four off he said the car handled better on the 19" than the 17" he used for the winter tyres, he traded in with the 17".
There is now no shortage of replacement tyres, and even 19" winters are now available, prices have also fallen.

Ps dealer told me all models now have nav.
