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.
I purchased this gps as new truck driver in the event I get somewhere new. I use a paper map most of the time to plan my trips. On one stop I forgot my trip map at a store. I used the gps to get home. It picked a route I never knew. The gps saved me time with a shorter route. I use the gps on all my runs and use paper maps as back up. It's not 100% accurate but pretty close. I recommend this to any driver. You can customize it to your liking.
