Hi Paynie....not sure what type of VE ute you have mate...But the one with the big screen (mines a Maloo) is quiet simple & you don't need to take it to a Holden Dealer...
*Firstly ign "On" & radio "Off"
*Then, hold 'track right', 'disc right' & radio 'on' simultaniously for about 8-10 seconds, you'll then get the service menu. In here you can activate either 2 channel or 4/5 channel speakers, 12/24 hr clock & a few other things.
* After doing this you can access fader "Front & Rear" in the main menu.
Not sure with the Omega or SS but by experimenting with with the first couple of steps you'll stumble across it...cheers...

Any help on finding out how to activate rear speakers on ve head unit.
Would like to fit in rear some extra beasty speakers and maybe an amp with a loc.
