aps navigation

[gaz6148]

i have a 52reg 2003 model cl600 it has a cd navigation system, now would it be a aps 30 or aps 50 version
i am looking to get the european cd set but not sure what system i have

If it has a large screen, I would assume it is COMAND otherwise it will probably be Audio 50.

A piccy might help
