Well if that statement is true that only 20 can be turned on at one time, I can see that Garmin will not change the default when you load a track to the GPS. Currently you have to manually go into each track that you want to show and change the default setting from DONT SHOW to SHOW ON MAP. I thought while accepting 200 tracks, that the unit would have the capability to show all 200 at one time and not just 20.
The other thing that I don't care for, is when you turn TRACKING OFF the current track will not show on the map unless you turn TRACKING ON again. Now that is just the opposite of the older Map Series GPSr's. The 76CSX showed the current tracks whether TRACKING was ON or OFF.
