If you drive a truck, there really arent a lot of choices out there for the iPad. This one is the very familiar CoPilot based version. It work basically the same as you would expect CoPilot to work, but takes into account things like the National network, bridge restrictions, hasmat, etc. It understands the challenges of driving a truck, and understands you cant just do a u-turn in the middle of the street. The App works very well, and is very responsive. You can update the app for things like maps right on the iPad, which is great when you are on the road. Just find a local wifi location. I dont like the way it announces streets sometimes, as it tends to state the highway number rather than the street name. Thats good on the highway, but in a city (at least the ones Im in), the street name is more prevalent. I like to know where my weigh stations and truck stops are, and having a special section to go to that lists Truck services, Truck Stops and Weigh Stations is worth its weight in gold. Note this app works just fine with your car, or even walking (you can set truck, car, bike, etc.), so no need to buy two apps. Its one of the only real truck apps out there, but its a good one!
