Comand Radio sound cutout

[Zeusy]

Hi guys,

Yesterday I got a new alternator put into my 2003 e320.
Since I left the specialist, I noticed when accelerating from a standing start or nearly standing start, the radio volume would cut off for about 2 secs and come right back on again. Nothing on command screen shows any error etc..

I had the satnav unit in the boot replaced yesterday also, as the previous one wouldn't read any discs...the satnav is now working fine...but this radio sound break up is really annoying...any ideas?

Now the battery - convenience error appearing yet again!!
I thought the replacement of the alterna6tor would fix that!?

The sound cutting out on radio is happening more frequently now and the parking sensors are flashing full and of again when this happens.

Help, anyone ideas??
