Good video, but still don’t understand how a GPS needs calibration for MPH

How do I do the time zone calibration? I'm in Idaho.

I love mine it's saved me countless times.
But it is just blinking now and will not work. The bottom right labeled A is blinking 0 the T is a steady 0, the S is at a steady 0, and the ml is just blinking dashes.
How the heck to I reset it? I've had the issue before but it always reset eventually but ever since I shut the truck down for like 30 minutes it's been doing it

bro how does it perform so far? ive used the exact same thing in my car but after 2 month, the GPS detection is a bit wacky now. It takes time to detect or certain angle to find the GPS signal then it can be use, if not it will not give any reading. Do you face the same issue and did you find a fix for it?

hi, I want a RGB or RYB digital with LED lights so that I can attach it to my car so that the cars on my back should be able to see the speed I am driving, the simplest speedometer without GPS and cheap one, I was not able to find one but please suggest me one.

does the usb cord have to be plugged in to work or can you charge it up
