Bye, bye, XM
First, they kill off the best channels, even the mildly alternative Fred, Lucy, and Ethel.
Now they want to charge for everything, including online listening (you know, for those people who work somewhere where their mobile XM receivers don't work).
XM NavTraffic never worked convincingly, although I think part of the blame is the Garmin devices' propensity to want to steer you towards traffic of which it knows the speed, rather than take a chance on a route there is no traffic info for at all. So in the metro DC area, you're routed straight to the middle of the nearest traffic jam, near 100% of the time.
