Let the navigation system boot up and get into a normal operating mode. 3. Leaving the system on (never turn the power off during these steps!!) eject the navigation DVD from your drive unit. 3. Load the new burned V32 disk into your Nav unit. 5. Watch your screen and be patient. Once it find the disc, the monitor will turn off. 6. A few minutes later, the monitor will turn back on.
