Any help appreciated folks.

sounds like the mode button on the steering wheel is stuck down, or the wire for it is pinched under the horn pad.

the mode button on the setting wheel isn't really a button with direct link to the radio. It simply produces a voltage which the radio's computer interprets and performs the request./

it is common for vy and vz steering wheel buttons to actually operate different functions as the get older and full of dust. EG. pressing mute, may make the volume increase. and pressing NEXT may make the mute activate.

Remove the horn and disconnect the steering wheel controls. then test. make sure you plug all the wires into the airbag before testing as without the wires connected and the battery connected it will trigger an SRS fault
which will require a visit to Holden or a TEch 2 to fix.

Always disconnect the battery before removing anything from your car....

Question.....how hard is it to remove the horn button to do this test,as the sereo had a major hissy fit coming home the other night,and I have now pulled the fuse to it as I was going to smash the bloody annoying thing because it was turning on/off at will and all the controls were nuts.

i wouldnt test the head unit with the air bag still connected with power as u would b risking it 2 depoly, almost like a ticking time bomb lol

Try wat spoolin said tho disconnect the battery and take out the airbag fuse aswell 4 safety and let the car sit there 4 half hour or so 2 make sure theres no power there at all.

The horn pad itself just uses spring clips that u can see on the back of the steering wheel so release them 1 at a time and after u got the air bag out (put aside) still conected just disconnect the steering wheel controls loom and put it all back 2gether, then test and see if its still doin it. If so then the problem may lay elsewhere but chances r u'll b able 2 rule out the controls or not i rekon.

they do have a button switch inside but as spooling was saying they send an ohm reading 2 the unit 2 tell it wat 2 do, from memory i think its 1.2k ohms 4 the mode button.
