Just swapped my concert s/d for 1 the same B7 A4 (i had a cd prodlem thats reason for swap)
now the new one works perfect but have to turn it on and off by the button ?
NHN any ideas
also the new one is from the A3 8P i just swapped the fronts the wireing info on the unit is the same as the one i removed
iv done this loads and never had this problem is there a setting on the radio or in VCDS that i cant find
