So since it’s gotten colder, I’ve noticed (as I have every year) that my stereo processes inputs noticeably slower when it’s cold outside. Anyone know why this happens?

Because the Vtec kicks in slower and that makes the blinker fluid slightly more solid, which creates a chain reaction for the carpet motors which transmits a signal to the headliner actuator gasket which also gives a slight electromagnetic pulse to the hydraulic radio pump which makes the inputs slower or whatever.

Did you change your radio fluid?

trUst Me imma doctor.

With that said, I could probably pass all that off to a non car person.

Does the whole system react more slowly or is it just the screen? Those older displays are definitely affected by the cold. Our old Mazda3’s radio display moves comically slowly when it’s really cold outside. The rest of the system shouldn’t really be affected, though the buttons might stiffen up a bit, which may act as an allusion.

Yeah the buttons ate slower too, but I understand that part. It’s one of those seven-segment displays in a 2004 Accord. It’s just the screen that’s slower.

I once passed off blinker fluid to one of my friends. No joke.

I told my mother that her blinker fluid was low, she believed me.

I’m actually going to print off one of these and stick it on an old oil bottle.

and one of these.

Someone more familiar with the technology could go into greater detail, but I am reminded that LCD stands for liquid crystal display. So I’d guess that the liquid must be thickening in the cold, compromising its ability to flow, not unlike motor oil.

If this is an aftermarket head unit, I might suggest removing the faceplate overnight.

Have you seen transformers?

You mean that CGI orgy of explosions and Michael Bay’s likeness?

The first movie.

Yeah cold = slow electronic crap. Just the way it is.

Except for me its the AC belt squealing for 5 minutes waking the neighbours.

Temperature is a measure of the level of activity of atomic particles. So, when it’s cold outside, the electrons in the wires move slower causing the effects you’re seeing

I thought cold is supposed to make electronics faster, like that conceptual absolute zero computer.

Unless your car is wired with superconducting materials, nah. Normal metal shrinks in the cold. If you make a pipe smaller, water will have to slow down. Same thing here

When you first turn it on? Maybe due to lower power @66% from your battery when it below freezing. With lower current running through the system it might take the electronics a little bit more time to boot up.

Actually, if you make a pipe smaller and maintain the same pressure, whatever is in the pipe must speed up.

this is it. If you pay attention you’ll find that the rest of the system is responding in a normal amount of time, its just that the cold LCD takes an extended amount of time to change state due to thickened fluid, causing a delay in DISPLAY of changes.
