I use it frequently and never had problems with it until now. I went out to look for a property in a rural location. I set the location and everything so I'm going where the thing is telling me to go. Well I had to go through some unpaved roads and the roads were in terrible condition. I had to drive really slow but it was too painful to hear the car go over the bumpy terrain. Once I reach the place, it's not even the correct one. I then found out the property I was looking for was 2 miles away from where the Nav indicated it was. It hurt my feelings when my car went through those crappy roads.

 

I know the feeling.
Very rarely does our nav system get a location wrong, so the 1% that it's not right, we can't get too upset about it. I would take my navigation system over the one in a MB anyday!!

 

Trust me, i doubt the navigiation is any better or worse than any other car.

I had the 2006 300C factory navigation, and it did the same. What was even worse was when i upgraded it to a Pioneer D3 Navi DVD head unit. That was just messed up.

Now i use my HTC Tytn2 instead of any car navi (Runs TOMTOM) and its actually much better accuracy than the car ones.

 

It doesn't surprise me that a rural location like that might be wrong, some of those areas are so poorly mapped once you get off the main road. Other than the XM NavTraffic issue, I am pretty happy with the Nav.

 

even with my garmin black box, it won't pick up new areas/streets, but it has never thrown me off course though...

 

I have to strongly disagree with this. I have found that Acura/Lexus/Infiniti seem to have the best in-car navigations in the auto industry. My parents had a BMW 7-series 4 years ago, that nav didn't even come close; same with the MB S-series they had 2 years ago. Now they have a Bentley Continental Flying Spur, and that actually has the worst navigation system out of them all. It doesn't even have street names on it!!!!

Keep in mind, when I say "navigation system", I'm not only referring to when you input a destination, but all of the features of the system. Current location maps, POI's, etc...

 

Well my dad's Infiniti M45 (2003 model) seems to be old school, and i didnt really enjoy even the aftermarket D3. I heard the Acura system is amazing. Time to give it a go/
