I was amazed at how many different hardware part numbers there were in just the 2014 model year and once my hardware was replaced, there was a software update for that hardware version. The dealer tech had to plug into my truck, gather the current module information along with my VIN to determine what it needed. Shop at: Here we have retro fitted 2016 Apple CarPlay Technology into a 2015 GMC Sierra. We are able to add full.

I searched, but cannot find out how to see what version of the Intellilink software my Acadia has. I assume this is something they update periodically. Does GM publish change notes for new versions of their software somewhere? Just wondering how all of this works.

I do know there are some glitches. My DIC display sometimes flashes off and then on again quickly. That's something that would be nice to have fixed in the future. Also, updates like displaying album art when streaming music from a phone via Bluetooth would be nice. This isn't like an android or apple phone where they push O/S upgrades, and you can choose to upgrade (or not). GM does create new versions of the software, and just about no one (not even most dealers) will be able to tell you what the 'most recent' version is or does, or the changes between versions. For the most part (with some exceptions) they don't offer 'upgrades' because their are new features, and they don't usually make features in newer models available in older models.

The update you might get would be a bug fix. (In certain GM vehicles there have been functionality upgrades for apps and such, but that isn't the norm). That said, they have been known to flash updates if a customer has a specific problem. Your DIC is likely unrelated to the Intellilink software, so it is doubtful they would update it just for that.
