Below is the update process I found posted on the a GTR forum for HDD based Nissan NAV systems. I am told that if A dealer claims over 30 min of tech time they are not being honest.
You do....
- Go to
NAVTEQ Maps ? Buy the latest map for your GPS SatNav , find your car and buy a license code Comes instantly via email.
- Take the code to the dealership with your car.
The dealer does....
- The Nissan Consult III diagnostic interface is plugged into the NAV System and first an update of the nav software (not map) is done, it can also update the CDDB info if you choose. (5 mins)
- The Consult III system will generate an 8 character code unique to your NAV system.
- The dealer will log into a the Nissan/NavTeq licensing site and input the code from your NAV system + the license code you bought. It will generate an third install code that can only be used on your car and within 3 days. At this point your license code will be used up.
- Perform the CIII update MAP and it will ask for the install code generated from the site.
- Install takes less than 25 minutes - unattended
- After the update is done the system NAV will reboot twice, write new bootrom ,etc.
- Done.
