Let's clarify on the terminology here first: AGPS refers to assistance technology that enables a GPS chipset to query relevant information (ephemeris/almanac) over a data link (mobile data/wifi) that offers more bandwidth than the satellite down link (~1Hz). With that, *if* you are travelling in situations with little satellite visibility, AGPS will be of no help, as the GPS chipset just has no beacons from satellites to determine which ones are visible and subsequently triangulate a position.
I think you are referring to the network-based positioning which estimates positions based on visible wifis and the radio cell the phone is currently connected to. For the scenario you are mentioning: What kind of "dark zones" did you drive through? Did you have wifi enabled?
