It depends what unit model do you have, and what it's firmware is eg US/EU, SG/MY or PH. If you have an asian unit that can read this type of JCV file, with most Nuvi models you can usually place the jcv file in a folder named 'JCV' (no quotes) in the .system folder of unit, or in the Garmin folder of the sd. If you have a unit with us/eu fw, don't bother because the encrypted jcv file will cause a crash & reboot error.
