Removing the UpperFilters and LowerFilters registry values from the Windows Registry is a likely solution to several Device Manager error codes in Windows 7, Windows Vista, and Windows XP.

UpperFilters and LowerFilters values might exist for several device classes in the registry but those values in the DVD/CD-ROM Drives class tend to corrupt and cause problems most often.


Important: Changes to the registry are made in these steps. Take care in making only the changes outlined below. While it's not a necessary step to complete this process, I recommend that you play it safe by backing up the registry keys you're modifying.

You might have a problem with the disk. Take the disks back to place of purchase and ask for a replacement set, or else phone Garmin and explain you think you have a bad disk.
