Laguna II Clock setting ????

Hi guys



So ive looked through the forum for an answer to my problem but havent been able to sort it out yet.



I bought my 03 Laguna II Techno DCI yesterday and theres only one thing thats annoying me, the time on the clock on top of the dash !



Ive tried setting it with the radio buttons, it lets me go through all the steps of putting the time right but when i press ok at the last step it comes up CLOCK SETTING ERROR.



Ive tried the other method of holding down the source button, i was there for 3 minutes holding it down and the time didnt start flashing, my finger was sore by then lol.



I have the GPS system on my car i dont know if this makes a difference, ive also read about another aerial being installed for the GPS signal as i let it sit saying calculating your route, it was going for 10 minutes by which time i got bored and set off as i knew where i was going anyway, but its a new toy so i had to try it out :D



So if anybody can shed any light on my clock situation id be most greatful.



Cheers guys
