How does one go about updating the maps on the NAV? I can't seem to find any info on it. There are a ton of errors around here on Staten Island I was hoping that maybe they would have an update on.

I was told at the dealership that maps are updated via XM over the air. I didn't get clarification if that was on a schedule or on request or what. I'm not sure at all about the accuracy of that statement. Can anyone else give input?

XM and NAV are 2 differents things, so no they won't be upgraded through the air.

You have to go to the dealer to obtain the updates vis usb or dvd.

If the gps is a garmin or tomtom or something else, the updates maybe available through them directly when available.

Not actually. XM is how your NAV can get traffic data. The newer GM Nav systems have a lot more modern abilities, so anything is possible. I'll look/ask around for more input on this...

Traffic Data and GPS/NAV are not the same thing... Ex. : On garmin GPS the traffic receiver is external so there nothing about maps involving with traffic updates.
