Hello...
I am trying to determine the current update status on my 2013 Avalanche LTZ NAV system.
I have read some posters say that the 2013 is a Hard Drive system, not a DVD or Disc system??
Others claim that the 2013 is updated with a DVD disc...??
Which is correct? If it is a hard drive based system, how is it updated? (flash drive perhaps)
If it is a flash drive update, can those be purchased from a source other than GM?
Thank you
