Summary: As a long distance truck driver I can honestly say the 720 is a very expensive piece of junk. 90% of the time it won't take me to my destination. It'll get you close. Thank goodness for Google maps. Putting in addresses is a challenge. Forget military bases. Once I wanted info about Bangor MA. I entered Bangor and it suggested about 5 different states with the name Bangor, but not Banger Main. It's almost impossible to enter your address.
Summary: Have had this device for 8 months is 75 percent dependable,has sent me on routes out of the way,but overall it will get you to the destination.Haven't had issues of device locking up.Seems like the maps need to be updated
