Devices that Include Truck Routes in the Mapping Software
The Garmin devices that are specific to truck navigation are the nüvi® 465, dēzl™ 560 GPS navigator and all models in the dēzl™ series, and dēzlCam™ and all models in the dēzlCam™ series.
The nüvi 465, dēzl series, and dēzlCam devices allow the creation of a custom truck profile containing the specifications of the truck, such as height, weight, length, and other restrictions.
No other Garmin automotive devices contain mapping software to support truck routes or low bridge clearances, with the exception of the Overlander® GPS navigator and the Camper/RV 660LMT navigator and all models in the Camper/RV series devices.
The Overlander has access to height clearances and weight limits provided the vehicle type has been set to a vehicle other than "Car" and the profile has been completed with the necessary information.
The Camper/RV series devices have access to height clearances and weight limits provided the vehicle type has been set to Camper/RV mode and a Camper/RV profile has been created. For more information on this, consult the owner's manual.
