I had a new 7-year Interstate Megatron battery put in yesterday and now I have a 24-hour clock instead of a 12 hour clock.

Anybody have any idea about how to reset the clock without going back to the dealer?

Thanks in advance!

 

It depends on what year your car is. If it's 02-04 then I think you hold down both the hour and minute button at the same time. 05-06 just hold the clock button down and it'll give you the option to change it.

 

Thanks man. That fixed it.
