In this video, I go over the unexpectedly convoluted process of upgrading the RAM on a Honda infotainment system from 1GB to 2GB. While normally I would say that upgrading RAM on a device like this wouldn't be worth doing, in this case, the main goal of this upgrade was to rectify a very common crashing issue these devices have when using CarPlay or performing other demanding tasks. This particular system is from a 2016/2017 Honda Accord, and runs a heavily modified version of Android, making it essentially nothing more than a glorified Android tablet.
