I have a 2003 mk4 astra 2.2 Sri, and in it originaly it had a ncdr 1100 head unit which operated the trip comp thru head unit, some one has fitted an after market head unit so now the trip comp and check panel don't work with out the head unit also can not set the clock as mfd doe's not have any buttons on, is there anyway if I was to get a wiper stalk with the two buttons on could I wire it up to the blue iso plug connector block on the main loom.
Many thanks
