Looks like it's Tele Atlas maps. No biggie.
I wonder how much more responsive is the MSN Direct is, when compared to XM NavTraffic? The NavTraffic isn't well integrated with the D3 when it comes to actually notifying of traffic incidents & reroutes. the D3 tells me of these incidents when I'm actually stuck in traffic and reroutes me back into traffic, which is kinda annoying to say.
If MSN Direct performs a lot better, I might have to make the switch.
