The coverage map report produces a map showing all the GPS data points recorded for one or more vehicles over a given period of time. The report is primarily intended to show where phone coverage is available.
Select the fleet (1) and the vehicle(s) to be included in the report (2). Then enter the start and end date/time for the report (3).
Note that the absence of data points does not mean there is no coverage at that point – it may simply mean that no car went to that point.
