After Replacement
WARNING: This page is about a different car, the 2016 Nissan Versa. However, it is still accessible from the selected car via links, so may be relevant.
If the AV control unit is replaced with a new AV control unit, the new AV control unit must be registered using the registration code.
CAUTION:
If the new AV control unit registration code is not registered, the "APPS" mode will not function.
