I'm not wondering how to set the clock, that's pretty simple. I have an actual problem with the clock.
1: It doesn't allow me to set it in 12 hour mode, it automatically puts it back in 24 hour mode.
2: It resets back to 0:00 once I set the time. After I set the minutes and hold it for the three seconds, or how ever long it takes to stop flashing, it goes back to 0:00. It might keep the time I set for a couple of seconds.
Has anyone else had this problem?

Get a Timex watch. Cut the straps off. Stick a velcro patch on the back. Stick the other velcro patch on the bolt head that is on your top triple clamp. Use analog. Replace battery every coupla years. Done.

 

That's a good idea and I'm sure it works swell, but it doesn't address the problem I have with clock on my speedometer.
