During the update, the system can stay (or hang) at the DV-1 splash
screen for a long time. If the system appears to hang at the splash
screen, it may be recovering from a boot failure.
Follow these steps to recover:

Wait for 15 minutes at the splash screen.

If the system does not automatically reboot, turn off the vehicle
ignition, then press the
POWER OFF
key.

Wait for the system to power off.

If the system does not power off, press the
POWER OFF
key
again.

Repeat this process until the system powers off.
NOTICE
You can also disconnect then reconnect power to the DV-1 unit, if
desired.

Once the system has powered off, press the
POWER ON
key
to power the system on.

Allow the system to power on completely.
Once the system has powered on, the software version may be a
much older version. A message may also appear stating that the
system has been reverted to an older version of software because
the primary version failed.

Insert a blank DVD and allow all pending video to be burned to
the DVD.

Once there is no longer any pending video, press and hold the
STOP/QUIT
key to eject the DVD.

Wait for the system to eject the DVD, then power off and power
on the system.
