I have called a Volt Advisor twice now (got the same guy 2 days in a row), searched the web and this forum trying to correlate the nav map version in my 2012 (201103) with the one available for purchase on the GM Navigation Disc order page (2012 Global A High Nav Disc Part# 22827639 $199.99). I can't seem to get get an answer. I would think that my vehicle, having been built in early May, would have the 2012 version of the maps. Does anyone know how to translate the version of the disc to the version displayed on the Volt config screen?
Thanks in advance for any light shed to this mystery.
