Garmin Dynamic Speed Limiter Solution

The E-Cruise Dynamic Speed Limiter (DSL) for Garmin is a Plug and Play device based on the Garmin FMI API.

Connect to the Garmin navigation device using the Garmin serial FMI cable and get access to the unique E-Cruise DSL solution.

The DSL set's the vehicles maximum speed to conform to that indicated by the road speed signs in the Garmin devices. If another speed is required due to safety reasons the speed limiter is deactivated by pressing the speeder past 90% for about 1-2 seconds.

The vehicle will then accelerate and exceed the maximum road speed.

The DSL will be activated and adjusts the vehicles maximum speed to conform to the Garmin road speed signs when the vehicle speed is below the actual road speed limit.

The E-Cruise DSL for Garmin can be installed in most automotive brands and models.

Currently it is available for more than 700 vehicles including cars, vans, trucks and buses.

The Garmin road speed data is not 100% complete why some of the speed limits will be wrong.

In such cases the driver must intervene and accelerate or brake to the appropriate speed
