Today i decided i'd update its firmware of my p2140 and it all seemed to work fine, but when i put it back in my car, it goes into shutdown mode approximately one minute after being on, like as if the battery is low.
Any ideas? has this happened to anyone else?
EDIT: Also does anyone know where i can get the original firmware .hex file from, because it used to work fine on version 1.0
Well what setting do you have on it so that it will shut down after a certain battery voltage?
