I have had an Aera 500 for a year and a half...I love it...have used it in the US and Australia as well as here in Scotland....however I have discovered a SERIOUS PROBLEM WITH THE AVIATION DATABASE....Where I operate the only Class A airpsace is associated with Airway P600...the Aera does not depict it...I can see that it does depict the Class A around London but not around airways...Jeppesen obviously can depict the airspace...as it does so on the GNS430 so it must be a Garmin issue....I have written to Garmin Europe and asked them to explain....This must be a MAJOR concern to anyone using the unit in the South of England...
