Thank you for that feedback.  I guess I did not ask enough questions about the GPS when buying the car, or my sales person was not educated about how to get GPS.  This is something I definitely would've added.  I read some articles online stating that you can buy the SD card to enable the Navigation for $795?  Does this seem accurate, or what you're saying is that GPS Nav is not something that can be added to the vehicle afteryou purchase it. 
  
Thanks!!
