My battery died, so I replaced it with factory battery acording to the directions. This all went fine. Then I started the car and the onboard computer and Nav system didn't come up. I get a white screen on the dispaly and the Nav cd keeps trying to load.

I'm pretty sure this is something that can be rest. Seems like a SFW glitch or something. I don't know how to reset the onboard Computer system. I hate to bring the car back to the dealer. If someone could help me reset the onboard computer/nav system I'd be back in business. Any help is much appreciated.
