Hello guys. Got an astra mk5 on an 04 plate. Got some issues...My steering controls dont work no more, and also my horn no longer works. The strange bit is tho, That everything seems to do something else. Like, If I press my horn, The stereo starts searching for a new station and says "Memory-FM". Also, If I try and change the volume with the steering controls, it wont work for a minute then all of a sudden, it will start changing the CD track. Any ideas what can be causing this? Maybe I need to reset the stereo with Tech2 or something?
