This Garmin dēzl 770LMTHD 010-01343-00 GPS features lifetime map and traffic updates and customized routing based on the size and weight of your truck, so you can easily determine the appropriate route for travel.
This is not my first truck GPS but it s my first Garmin Truck GPS.I found it to be very easy to use. The graphics are great and the 7" screen is wonderful. It takes the guess work out and puts you on the best path.I highly recommend this product
