I just used my N810 to navigate from NY to Chicago. So here is my experiences...

First, I got a GPS fix with the N810's built in GPS within about a minute and a half while driving from a cold start. The weather was snowing so I was surprised to see such a quick lock.

The route calculated perfectly. Voice guidance was pretty accurate in giving prompts about distance with upcoming turns and exits. I didn't have one missed turn or exit so I was happy. Got me exactly where I was going on a long trip with no mistakes.

In Chicago, we were using my friends stand alone GPS (Mio - don't recall the model number) and we were searching for a "Trader Joes." The stand alone GPS could only find "Joe Trader" so we thought it must be a typo. Nope, it wasn't. So we lost about an hour after fighting traffic. We go home and I grab my N810. Open up map and search for "Trader Joes" and bam... like 5 locations come up. I was totally shocked that my N810 could find Trader Joes but my friends stand alone GPS could not.

This is strange... I had to make a quick trip to the post office so I grab my N810 and start map... do a POI search for post offices and tons come up... cool. But what sucked is that the closest one map could find was 3.3 miles away. I knew one was closer so I hop online and sure enough, 1 is only a half mile away. And what sucks more is that map had a post office POI icon where the post office was on the actual map, but doing a POI search could not find it.

Another thing I'd like to see is the ability to change the pointer color and remove the ring around it. When you are using the day setting, the color of the pointer is not much different than the background color... not a big deal, but if it were red or blue it'd be easier to see at a quick glance.

So even tho the map application has a bunch of stuff that could be done to make it a much better app, I still use it and like it. It's got it's +'s and it's -'s.
