So I have a question how do you update the gps system in the g37 sedan? What is the process?

 

also it is a 2013

 

Navigation is updated via DVD on these cars, order it here: https://infiniti.navigation.com/prod...InfinitiNA/USD

 

I vaguely recall these being on sale periodically. Maybe during the holidays? I still have the original maps that came with my MY '12. The area around here has seen some changes since but more than likely these changes haven't made it into the update yet.

Here's a good deal on a decent garmin unit... I own this unit too.
