2005 Land Rover LR3 HSE

We had an unexpected surprise from our Land Rover LR3 when the nav system screen went blank except for the notice, "HLDF CAN BOOTLOADER, waiting to start download." While malfunctioning, the LCD yielded a blinding white screen while driving at night; for relief, one editor covered it with a CD case. We made sure the system map disk was properly installed and tried without luck to reboot the system, before making a special trip to the dealer to have our unruly system inspected. It turns out we didn't need anything but a simple software update, which took the dealer about an hour to perform. Our service adviser said Land Rover did not and has no intention of notifying owners of the need to have this update. However, after checking with Land Rover, it appears our early production vehicle was an anomaly--it's had fewer than 10 with this concern and has since corrected it. But what if we'd been lost and needed Rover's nav system to get us to our destination? Other than this, the big Landy has been flawless and is signed out for weeks in advance.
