I did as you said and called Jayco, unfortunately the customer service people don't know where the NP401 Clarion navigation head unit is installed. It used to be in the passenger side kick panel but apparently that isn't the case anymore. She had to send the question to the second level engineers. She also commented that I may have to have the dealer disassemble the front of the motorhome to access the navigation system for updates. I certainly hope that isn't the case as that would be stupid expensive. For people who have 2013 and earlier Greyhawk units with the Clarion system I found that you can indeed get free updates from naviextras.com. You need to register, download the Naviextras Toolbox onto a notebook computer take it out to your Greyhawk, plug your PC into the navigation system or pop the SD card out and into your PC. That will allow you to update the system. Unfortunately, they don't know where they installed the navigation head unit on my 2014 model. I will update this thread when I find out.
