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
Were you messing around with the service menu? I had a similar problem after I pressed a "Loading" button within the service menu. Do you recall what you were doing prior to this message apapearing?
