I am going through the manual and will report back if I find anything........hope it's not the on/off button for those suffering from auditory schizophrenia...hmmm I just check my 2017 HP has it too but I have never noticed it. Interesting
I probably will not use Apple CarPlay.....I have my SD card with all the music I need ( > 5000 songs)......thanks for the info Russ. At least we now know how to reset our multimedia system if it crashes.You should have Apple CarPlay it came on 2018 models. I never use it because I don’t like plugging my phone in when I can just use Bluetooth, doesn’t work unless you have your phone plugged in.
