If we were blowing the budget, the Kenwood is the navi we’d have in our car. It comes packed with features, and is the only head unit on test to include digital radio.
The Garmin navigation is the easiest to use, with a simple screen and the ability to split the display to show your music as well.
There are TMC traffic updates, junction view and lane assist, as well as Bluetooth hands-free calling and iPod connectivity.
The menus are lovely to use, but it’s an expensive option.
