Hey ive had my Astra MK4 for about a month now, and i have noticed that on some days when i turn on the car the clock on the display is about 10 -15 mins slow.
I have changed the time to the correct time so many times, but it still keeps going back.
I just noticed the other day when i had the radio on, the wee clock symbol with RDS came up and automatically fixed the time.
Does the clock only keep upto date with the radio on? Or should it be correct on its own?
Any advice would be appreciated.
