The price depends on the desired coverage and is pretty steep. It is aimed at corporate and upwards.
Plates (approach and airport taxiways) are part of the service and included if elected as part of both the Garmin and Avidyne glass packages.
Both use the Jepp plates and in Avidyne's case the plate in isolation can be displayed on the MDF showing the aircraft's position on the plate in real time. Makes it very easy to fly almost any procedure
. The vertical profile can also be displayed but the aircraft is only positioned on the plate horizontally although obviously the step downs are shown on the plate. The service is updated monthly and well worth having.
