How do l turn off the satnav COMAND 'voice'?

[CycleSi]

Got a 2004 SL55 AMG with Comand DX 2 (l think?) and l'd like to turn off the 'voice' when using satnav and just have the map, etc

lf l mute the sound then l obviously also lose the radio/CD. l've found the setting which allows the 'voice' to be quieter but l don't want it on at all.

Any ideas/advice?

Thanks.....

IIRC when the voice is talking, just turn the volume down on the COMAND unit. The simple way to do this, is just get it to repeat what it's just said.
