Hi, have just recentley aquired a Z4 3.0i complete with naviagtion system. Went out in car Friday & used navigation system. Sytem works ok but i would really like to mute the naviagtion voice & just monitor the display when required. I know i can go into settings & adjust the navi volume down to min but it still outputs a faint voice command. does anyone know if its possibly to totally mute the voice command & if so how ? Other cars i have driven with standard sat nav sytems allow me to do this but my Z4 does not appear to be able to do this. Its the mk4 professional sytem with v32 software & the latest disc fitted.
