I have been messing around with my AvMap EK IV in the car and have noticed the GS is about 5 mph slower than my speedometer and my garmin auto GPS... The garmin and speedometer match. any ideas as to why the avmap seems to be incorrect?
 
as much as I hate to admit this...I just checked the gs again and yes the avmap is in kts. that would explain it. thanks
