Pretty bad 21

So here the battery does not take more than 15 minutes. When plugged into the cigarette lighter she starts directly in operation
and time soon impossible or very difficult to spend plugged in menus. as the battery is very short so the date should always hand it back and if we leave it permanently connected bug and the only way to do this is to disconnect and remove the battery so the date hand is a circle endless, me I have forfeited. okay it's cheap it's finally me zieppe.
