I live in Southern California, I know where Disneyland is. I am still not over the high of having navigation, I use it if I go to 7-11 to get a Coke.
I put in Disneyland, and it is sending me 21 miles out of the way. I thought "Ah, the NavTraffic is saving me time, yep." Then I checked and there was no traffic. I hit fastest route, shortest route and they both came up with the same identical LONG WAY around.
For anybody living in SoCal: If you live in the IE and want to visit the Rat, you'd take the 10 or 60 to the 57 South and exit Katella or Ball and badabing you see the rat.
The D3 does recognize the 57 freeway, and even when I was on it, it was telling me to take the 60 east, then the 91 east, then finally surrendered when I exited Katella off of the 57. The entire trip, it kept trying to tell me to go the long way around. Make a u turn, get off here, go here no wait, back, take this exit, it was more annoying then my wife.
Then when we finally get to the Rat, my wife says "Well that was a thousand dollars well spent.". Same thing on the way home. I actually got on the 57 freeway headed North, then hit "Go home" and it still wanted me to take the first exit, and take the 5 north.
Even when it plans out your route, it shows you a dark wide red route on a large map. You can see the 57 cut straight south to your destination while the I5 goes our and around like a curve ball.
Strange.
