The radio cycled it’s power while I was sitting idling in a parking lot. It went off, then came right back on as if I had hit the power switch.
That happens to cars I test pretty regularly. Not just GM products, but all brands. 2020 Nissan I was testing today did it.
Newer cars have a lot of ways they use electrical power. The computer probably prioritizes what’s allowed to be on and what must be off when there is a competing need between something safety related (like the engine) and something that is optional (like the radio). That’s my guess anyway.
Radios arent just radio’s anymore , they are basically a laptop built into your dash with a operating system . It is like getting a BSOD on your laptop and we all know how often that happens .
