Garmin 496 Smart Airspace
I was about to sell my 496 to a friend who was asking (when I took him for a flight) what the different colour lines mean. To be honest, its never occurred to me, I've always just worked on the basis that the "Smart" airspace turns the lines bolder if you are at the same level as that airspace, which is obviously the case but I wondered if there was a map key or something for the 496? There's nothing in the manual and I just spoke to Garmin Europe in Southampton who sounded unsure too!
Any help much appreciated!
