Caliber RDN893BT
Not only is the Caliber clumsy to use, it’s also pricier than the Clarion and JVC.
The SD slot is taken up with the sat-nav’s maps – you can’t play music from your own card and run the sat-nav at the same time. Plus, you need an adapter to play music from a memory stick in the front micro USB slot.
The sat-nav has speed camera info, but no traffic data, and there’s no way to split the display to see what music is playing.
