Kaui's video: How-To - 14 15 Silverado Sierra Android Auto Apple Car Play and Denali Cluster OEM Upgrade

The 2014, 2015, and some 2016 Silverados did not come with Android Auto/Apple Carplay functionality. This is the process to retrofit your older Silverado with the newer tech allowing you to run Google Maps/Waze and other music apps directly from the stock 8" infotainment screen effectively futureproofing its media capability as AA/CP run off the software on the phone and not the truck. Everything looks and works as factory like the truck was a 2016+ now, and the cluster is upgraded over the other options available to the Silverado. The radio module, HMI module, and jumpseat console USB had to be replaced, and to get full functionality of the steering control buttons, you need to replace the cluster as well with the Denali/F-cluster. It may be possible your steering wheel controls work without having to upgrade the cluster as well. I've heard mixed results of the old USB ports working with Apple Carplay and not AA, but I found a new USB off a CT6 for $40. The radio module, HMI module, and new cluster had to be sent off for programming, which is VIN and car option specific (like parking sensors, HUD, etc). Check out the gm-trucks forum for more information, as you cannot simply buy parts off ebay and slap them in and call it a day.
