Radio and Climate Control light delay

Hi everyone, I was sitting in my Tacoma after the gym and I turned the headlights on and the climate control lights on the knobs came on and a split second later the radio head unit lit up. It is doing the same when I shut the headlights off as well. Looking to see if anyone ever ran into this issue. I never had this issue before and I have a factory head unit in the truck. Anyone have any ideas to troubleshoot this?

Thank You!

 

It's probably just the circuitry charging up.

 

Thinking about it and I seem to think this slight delay is normal... Are there any other symptoms or issues with the stereo? I'm assuming that it works normally after it is booted up, correct?

 

The radio did take a 30 seconds at first to go from black to lit up then worked fine. The only issue I have with the radio itself is the volume knob does not click when you adjust volume and the volume jumps up and down when turning the knob. This has been and issue since I owned the truck.

 

Them lights will flicker on and off at random....
That's traditional Toyota signature lighting effects.
It ain't gone hurt nuffin'
Mine does it all the time.
