When sitting in the car with the ignition on but the motor not running, I can hear a fan coming from the dash. It sounds like a computer cooling fan. It also sounds like it is coming from the area of the nav screen. Is this normal? It stops once car is started or completely turned off and door is opened. Thanks.

I had the same issue.
It's the radio fan.
Dealer quoted me 2000 to fix it.
my initial post about it below said 1,000. which is incorrect, they later said it was about 1500 for the radio itself and 500 for labor.

On that video it is super loud. For me, it is no louder than a laptop computer fan.
