NAV System Version??
 

How do you tell what version of software and data is installed with the NAV program? I have a Equinox 2011 and we had issues with the system - bought the car new - finally dealer replaced the entire system, radio, hard drive computer, etc. I would like to know what version is installed. I travel a lot and the system is missing a number of roads, etc. so was considering getting it upgraded. Ya it's really pricey to upgrade it but the traffic notices for road delays is nice - if you are traveling a lot!
It's the LTZ model with the in dash video display.

This was a replacement for our loyal, great running, would have bought another one - gauges quit working So WHO NEEDS gauges anyway :) - 2005 trailblazer which had 350,000 miles on her!
