Updating gps data gm vehicle
My biggest question resulted because the nav system did not seem to reboot or show an "animated screen" as described in the directions - it went directly to the nav screen, which looked the same. When you do "config" == "Map database information", it gives me V. It took the guy at the call center quite a while to answer the question I was asking, and he was not familiar with the Volt.
After the install, the nav system was rebooted as requested and it did work properly on a short drive.
Instructions indicate that disk one of the upgrade is supposed to take about 80 minutes. if you are going to remove it quickly you need to be watching closely.
You have to enter the Update Key to start the update. Also, I had to enter the code twice because my code started with "0EB..." and I figured that the 0 represented the numeric 0 vs the letter O, or maybe it was the other way around. If you do not reomve the disk quickly, the disk will remain extended from the disk player until you remove the disk.
If you plan to install the map update I would suggest that you leave plenty of time and also if you read the instruction documents closely in step 8 "After Disc 1 update completes, the disc will automatically eject. Yeah, they lowered the price to 0 and released the 2014 version so I got the update for my 2012 as well.
The radio, climate, and EV functions remained available during the update.I too updated my 2011 Volt nav system software without problems, leaving the vehicle plugged into a level 2 charger, with the climate control and lights off, in my closed garage, with the vehicle locked.
