Can someone please stop me from tearing out my receding hair! I have not been able to change the clock on my Fiesta Zetec 1.4 June 08. The handbook does not seem to be in agreement with the car. It tells me to use the H and M buttons next to the display to make the change. I have no such buttons. What I can do is press the clock button which causes the LCD display to flash and by pressing the > button the hours figure on the clock start to flash but I cannot find how to forward the hours by one to take account of the recent hour change depite trying what seems like every button available. Thank you.
