Someone (??) should probably start an official Nav System thread. Good, bad, how to use, updates, etc. Until then though...
I guess I've mixed opinions to this point. There are some cool features:
During guidance, it displayed the highway directional signs (you know the green ones) and used graying out as a visual of which lanes/exit to use. Pretty cool. Not sure of these visuals are part of the nav data or captured by the cameras? I'm thinkin it's the latter. If so, very cool. Or maybe I'm just too much of a tech head.
On the negative side:
The map scale doesn't seem to adjust automatically. For example, on the highway a map scale of 2-3 miles seems reasonable. Whereas on the side and back roads, 400-500 ft is best. At least I haven't found a way to make it do this. I've played with all the settings. My VW did this.
The "traffic" display... I *think* we see a red outline on the road when there is traffic or congestion. You really can't see this outline unless you are zoomed to .5 miles or less. Again, not much use when you're on the highway or a long trip and you want to see 5-10 miles ahead. I'm open to suggestions...
The "Avoid" option. Haven't figured how to use this thing. One, it's hard to find when you're driving and two, it's always grayed out. Again, open to suggestions and certainly, corrections...
