No sound no voice command no NAV voice

[jlforlife]

Hi there,
this morning i went into my X, i realized my CD is playing but no sound. I decided to drive off anyway. I noticed the iDrive is really slow as i was trying to switch to radio to see if it will work. Still audio output. I tried the voice commanad, nothing happened. I tried the sat nav, it works but no display in my HUD and no voice. I pulled over, shut down the engine, got out, locked the vehicle, unlocked, put the key in the ignition this time (forget about comfort access) and it still didnt work. Everything is really slow.

Is this going to be a major problem? ANyone had similar issues before?
thanks
Josh
