How to downgrade NAV Version?

Hi,

I recently downloaded the 4.73 NAV DVD version and burned it onto a DVD+R DL. After I put the DVD in, everything looked OK and it was able to install. However, the error message "Error reading disc, (Incorrect DVD) Contact your dealer" pop out when it tries to boot the NAV. I was wondering if anybody had any luck burning the ISO or is there anyway that I can restore to the previous version?

Thanks for your help guys

Thanks man. I tried earlier to use the original NAV dvd that it came with my 07 TL, but an error message indicated that a "newer version program was installed." I'll try and unplug the battery later and see if I can get this thing fix.

you can force load it:

1. Go to your car.
2. Turn your car's ignition to ACC
3. Insert your old navi disk
4. Go back to the driver seat, the display will show some dvd read error, now press and hold "GUIDE" "MENU" and "CANCEL" for approx 5 seconds to bring up the diagnostic menu.
5. Wait another 5 seconds to let it load up completely. Press "version" button on the screen
8. Press "LOAD DISC" to load your old disk back into the system.
