I have just recently purchased a landcruiser that has a GPS/CD/Radio in it where the previous owner does not know what brand or model the unit is.

Can anyone identify the brand of it?
The second picture shows the navigation option. If you look closely there is a lock symbol located in the top left of the screen. I cannot use the navigation system due to this "lock". Can anyone assist in telling me how to unlock it? I have tried resetting the whole unit and disconnecting the car battery.

Thanks in advance
