Use to work just fine. Now its terrible, complete trash. Customer service is horrible. When they finally answer the phone they are no help. I have the newest iPad just for the eld book. Everything is updated but some how the eld disconnects and I have to reconnect it while driving. The Eld book doesnt read my drive time at all. Stay away from keeptruckin. It's always the drivers equipment fault. Never there five dollar black box.
