Clear, easy-to-read speed at a glance - with a 3.0-inch HD LED large-font display
The 3.0-inch full HD display uses large LED characters and a shading plate to maintain legibility in bright daylight while keeping backlight soft at night. Curved screen geometry reduces reflections and keeps the display low in the windscreen line of sight.
Instant speed checks without looking away from the road make motorway and urban driving less taxing. Large font reduces the need for prolonged glances, improving situational awareness.
Reliable speed measurement - thanks to GPS and BeiDou dual-mode positioning
Dual-mode positioning uses GPS alongside BeiDou signals to cross-check location and speed data, producing quicker refresh rates and more stable readings than single-satellite solutions. Firmware handles real-time updates to avoid visible lag.
Consistently accurate speed readouts suit drivers who need dependable data, such as delivery drivers or regular motorway users. Fast refresh means speed shown closely matches actual vehicle speed.
Quick, non-destructive install - with USB plug-and-play and non-slip pads
USB power and an included car charge adapter allow plug-and-play operation, with automatic power synchronisation tied to engine ignition. Non-slip pads secure the unit on the dash without screws or permanent fittings.
A straightforward fit means minimal setup time and no vehicle modifications, making it simple to move between vehicles. Automatic power synchronisation avoids manual switching and preserves battery behaviour tied to ignition.
