Just had a columbus unit fitted in my VRS se. Got the unit off ebay. When i put the nav disc in should it copy to the hdd? If it should it doesn't. when i put a mp3 disc in or a sd card it just sits on a screen saying system starting, but the music plays. Me thinks there is a fault somewhere .Any help would be great. Cheers

Try doing a reset by pressing < > i at the same time.

If the navi information is already loaded and is the same version as the disc I believe it brings up a message saying so. hope this info helps and you get the Columbus up and running.

Already tried that and nothing happens.also tried turning on with no key in ignition and holding setup for 15 seconds. Again nowt happens. Starting to feel iv'e been ripped off by the eBay seller. Thanks for your reply.
