You have a few corrupted files internally. Contact Rand Support to
obtain a new update SD Card to upgrade you to the new version and maps. The update SD Card will not remove your user
data. Be sure to have your serial number handy,

The download did not go correctly. You have a unit that is
missing or has incomplete files. Contact Rand Support and they will send you an
update card. It will not delete your user data and it will upgrade you to the
current version and with new maps. Be sure to have the serial number off the
back of the TND (bottom right) handy.Thanks Mark, Rand Lead Beta Tester
