About the GTM60 HD:

To all Canadian Users (well, at least those living around the GTA, but I believe all those far from the US border), don't bother buying such accessory as it has absolutely no impact in traffic info on 3490. The reason is because we are not covered by such service. Believe me, I tryed for several days and returned the thing. It shows exactly the same info the GTM36 it came with the 3790 shows. Seems that Garmin gives us no adds to sweeten our sore pockets. That was the same with our 3790's we had no adds while our US brothers had Speed Limit configuration. Oh, well!! why complain? Garmin has a lousy C.S. (So it's said, honestly I didn't use it so can't complain - yet).
By the way, did anyone see the bird's eye view mode? how does it look like?
