I've had the anywhere map ATC about 1-1/2 years and am very happy with it. Lots-Lots-Lots of features. I've also installed the pocket plates program which give me all the approach plates (I move the unit between a citabria and a bonanza). It can be updated every 24 hrs, if you like, which will give you TFR's. It also can be used with xm weather, although I do not have that feature. It also gives the airport diagrams, also geo-referenced, just like the pocket plates. There are many features I just don't use, such as the glide slope to any airport, hsi etc. The database subscription is $ 115 per year.
Things I don't like about it. It washes out in direct sunlight. Not much of a problem in the citabria, but more so in the bonanza.
It's database lacks some rivers and lakes. It is slow to respond, when you make a fast turn it has to catch up.
If you wait a month or two I'm sure you will see original ATC on the used market at bargain prices as Anywhere Map has announced a new 4.3" HD unit. I'll probably buy one of these when it comes out.
