Its curved, low-profile housing and automatic brightness adjustment reduce glare while delivering readable, real-time numbers and alarms. Designed for most post-2008 cars (with some brand exclusions), the unit plugs in for a non-destructive, plug-and-play installation and offers customizable alerts for overspeed, engine temperature, voltage and driver fatigue.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the B3 improve visibility and reduce distraction?\u003c\/h3\u003e\n\u003cp\u003eThe B3 places key driving data into a single, easy-to-read display positioned on the dash so your eyes remain closer to the road.
