Go to "tools/options/sounds and "play this sound"

Make sure your volume is turned up on your ipod and in the car make sure nothing else is playing. Also check your instruction book and if all fails take your car back to where you bought it from and explain what has happened also make sure it's properly pluged in!

It suddenly stop the sound. You can see but not hear anything. I uninstalled it and installed it again, but it is the same, this is what appears: Error code #E0601003 Thanks

I think you have a multimedia keyboard and you hear nothing when you try to use it or your keyboard is not working.Well if you remove the keyboard do you hear anything from the speakers?You might want to check the volume levels,make sure nothing is muted.The device you are trying to play make sure the levels are turned up.
Good luck

i dont know if this helps at all, but you should try to use a earpiece.

try installing the computers drivers

check volume level or mute button

Check to make sure your settings arn't muted, audio driver software isn't muted, or the volume is set to low volume.

May be the driver for yur sound card are not installed....
