So is the units found in other GM brands, Lexuses, Toyotas, Land-Rovers,... "- There is a DIAG screen that can be accessed when going in the NAV screen, then going into MENU and then touching the screen and holding your finger for 5 seconds a bit right to the yellow Nav. Menu that is on top (about half an inch right of the word Menu) - From that DIAG menu, there are 3 codes that are known to be working : 660, 9448, and 295660 - The difference between the 3 codes are little: 660 : diagnostic menus, no back button to go back to the menus (you have to turn off the car to exit this screen) 9448 : diagnostic menus plus a button to update the software and a back button to go back to the menus 295660 : diagnostic menus, no software update button but a back button to get back to the menus - When going into the DIAG screens and back to the menus (if you use code 9448 or 295660), the hard button on the left of the unit are not backlit anymore until you turn off and on the car - Nothing in the DIAG screens that let us use the NAV while moving, nothing about playing video DVD either (there are really only diagnostic tools there). - Other Denso units found in other brands have different diag codes. What work for one unit is not working on ours. There are codes on Lexuses, Toyotas, Range Rover that enable address input while moving or DVD play, so there is hope we can find a similar thing on the C6 unit. - On Toyotas that have the Denso unit wihtout the touchscreen, the access to the diag screen is different. You need to use a combination of things, like left signal, lights on/off... (I don't know the exact combination)." So I guess their is still no way of bypassing the NAV system. Hope this helps.
