The 2nd day I owned my 2015 All Terrain I programmed in the 6.8mi drive to my office, there were 3 MAJOR errors in the mapping. One error was attributed to an interstate name change dating back to 2012. I was so pissed, then I found out that GM disabled the HD radio (advertised feature on the window sticker) and the iPhone interface was handicapped. Just unacceptable. I called the intellilink support line and they were less than worthless. I asked then for a map update at least, GM declined and said I could ask the dealership and hope they give it to me on goodwill (aka make the dealer pay for it) which is chickenshit if you ask me... The dealer did their job, GM set the expectation with the consumer.
