We just got them a few weeks ago, no training they just sent us out with them. Basically works the same although I've noticed I hit the 3 key alot when hitting arrow down, which resulted in a lot of stops having room 3 as a delivery point. Best of all that signature key is still in the same spot that many have complained about for years, so much for listening to our feedback on how to improve the diad. But it does scan around corners and such, and is much lighter, but the new pouch is to bulky for me. For now I just slip in my vest pocket instead of using the pouch, are some really leaving it in pouch when driving rather than putting it in diad slot? Thought DIAD had to be put in holder on dash while vehicle is moving.
