Tempo is a GPS speedometer for vehicles that don't have an accurate one: Land Rover Defender and Series, Toyota Hilux and Land Cruiser, Jeep Wrangler, Suzuki Jimny, Mercedes G-Class, Nissan Patrol, classic cars, tractors and anything else on big tyres with a dial that lies. Speed comes from GPS, accurate to one km/h or mph, on a large analogue dial with a needle and a digital readout – or as one enormous number (HUD style) when that is all you need.
