Hi, I seem to have an issue with external maps used with the device, after update to latest official 8.0 version the device remains at loading maps/courses screen (with garmin logo) and can't go into operation. Only hard reset helps when I try to shut it down. When SD card was removed, all started correctly, although all profiles were removed :( This update although very nice does not make me confident I will be able to use external maps I purchased any chance this will be looked into in the near future?
