ASTRA H Temperature Dispaly

Hi, I recentely removed the radio from my new Astra H and after putting it back in, i managed to reset the time, date and radio station, but instead of having the temperature displayed, i have the letter 'F' marked instead. Is that some sort of failure? Is there a way I could get the temperature back please.

Thanks

Go see your car dealer and have them plug in their diagnostic tool to fix the problem. It is quite easy with the correct equipment
