Does anyone know if satelites in the sky get updated information about road closures that get sent to our navigation that lets it calculate the closure into the route?

My second question, if I were to go to a race track, does the track show up on the screen. By this I mean real race tracks like buttonwillows or laguna seca?

Thanks

 

No and nope.

 

Does Infiniti offer a serivce like NavTraffic on the M or Q ?

 

Not yet.

I'll elaborate the "no," and "no" a bit.

The navigation system is based on the GPS system as well as hardware such as a gyoroscope, wheel speed sensors, and a few other items to maintain accuracy. The sat signal is a one-way transmission from the military GPS constellation of sats to your gps receiver. This is different from the systems that give you road closure, traffic status, etc. These traffic flow systems are augmented by data from XM, for example, which is separate from GPS.

As for a track showing up on the navigation system, it might show up as a single destination "dot," but the actual track probably won't be in the system. If it is, cool. I doubt it though.

 

Portland International Raceway's track layout doesn't show up on my '04 nav, or on my '06 Acura MDX nav either. The road to the paddock is there, but that's it.

It might...To find out you can just use the joystick to move it to any track in the US. It might show the track but it might not recognize the track as a usable road (color of road will be different than regular use roads). So "Bitch-en Betty" (voice prompts) will not tell you to turn left at the hair pin turn.

I was amazed to see that the runways and taxi ways of La Guardia Airport were part of the data base. In fact yesterday at La Guardia I accelerated to 155 MPH before going airborn...no not in my G...that will get you arrested.

 

Looks like Will and Mike are correct...I just zoomed to Daytona and Indi...they just look like big parking lots.
