Could some one help me which one to buy?

I am going to buy a sat navi for my passat. I found two models through google, but I don't know which one to buy. The price almost the same. Pros and cons, it's really hard to decide...

The first one, a unit with iphone style and fashionable design.

The second one, I found a demo online, there is no video for it.

All a bit way out for me but how do you buy them, I can't see a related site for purchase, and what are the dimentions, how wide, how high etc, sure do pack some features in there.

the sat nav is only good if it has aust maps you can buy them but it gets a bit pricey

3 is it new
