maybe someone can tell me where i can find AUX conection!?
do i need to take sistem out to rich it?????????

Its an old post but ill answer it for completeness.

The AUX connection on the navigation system is a mystery there isnt an AUX connection as such on the rear of the unit. It will more than likely be enabled when the AUX accessory is connected to the CD changer bus, but there isnt anything available.

Anyway, the CN+ unit is removed by placing two small screwdrivers in the two holes either side of the cd slot.
