Tried and that didn't work. Could it be that the software is broken? even adding a new disc may not help, what do you think?

I have a 2004 GX470 with the original DVD nav disc. My nav screen is no longer working and it's displaying the following error message "Error: System unable to access the program...Incorrect program disk. Please insert proper disk" (I've attached the screen shot below) I unplugged the battery power so the system can restart and I still get the same message. I took to the dealer and they want me to change the entire DVD and nav component at a cost of $1K. I don't understand why I need to change the entire system. Has anyone seen this error message before? Do you think it can fix by updating to the new DVD version? Thanks for the response

I just bought an IPOD and am looking to find out the same thing. Is it possible to have a technician installed an AUX line-in so I can hook up my IPOD directly into the AUDIO system without going thru FM transmitter or tape playing. Any feedback would be appreciated. Thanks.
