Factory vy stereos

[03sprint]

Hi All
I recently purchased a factory vy single disc stereo off ebay, I have plugged it in and all is well except there is no fader on the display for the rear speakers! Is it possible the stereo I purchased came out of a ute? are they different? and if so is there anything I can do to action the rear channels.
Cheers for any help. John

ur right the unit u have is from a ute and needs the 2 rear channels unlocked via a tech 2 unit that should only take 10-15mins 2 do. Greg (from ASR) has 1 of these.
