Hi all, I've recently bought a 2006 GV with the RB3 stereo / Sat nav. I didn't have a disc with it so I bought one on ebay. When the disc arrives, it came with an update CD that had to be carried out first. I did the update and the stereo rebooted. It then continued to install with the percentage rising. When it got to 100%, it said it needed to reboot agaon, counted down from 3 and switched off. It has not come on since and I can't turn it on. I have tried a soft reset (seek down, nav and eject) and I've tried disconnecting the battery for 30 mins and still nothing. Have I buggered it to the point where I need to buy another stereo or is it recoverable. Thanks in advance Mike
