Audio Hack - Infiniti Sound on GM vehicles

I was recently made aware of the Inifiniti Sound app in the Google Play store for android auto. Installing this app allows you to adjust your audio with a 10-band EQ even for the Hummer EV (while parked). This has been universally agreed to be a total game-changer for the audio system as it allows a much improved overall sound for music playing through any source as long as you adjust it correctly. I wish GM would come up with a version tailored to the Hummer and add some DSP options, but I’m sure Bose would frown on that.
