Portability is one of the most important factors in satnavs – if you don’t want to stash it in the glovebox once you’re out of the car, you’ll want a device that’ll fit in your pocket, or bag, at least.

Well this is slimmer than an iPhone 4, which puts it up there among the slimmest satnavs around, yet this stunner has a huge, 4.3-inch screen, for easier viewing of upcoming turns. 

Traffic updates are free for life, thanks to an external receiver, though they’re not updated live, and you get maps of 43 European countries.

Graphics are photo-real as well, using Google Maps-style snapshots of streets, so you can see the roads as they appear right in front of you, making it even easier to get the correct turn.

Portable and punctual. What more do you want?
