Bolero issue

First issue after 1 1/2 years and 36000km later.

Getting of work the radio turned on but no sound, volume sign not willing to go higher or lower it stayed on 1/4 on the scale, changing station on radio or on steering wheel it was slowwwwwww changing, but still no sound. On /off , on/off and nothing. All buttons worked on the bolero but very slow chnaging to whatever I choosed.

Got home, weird driving without music, got the vcds and their was a error from can gateway to radio, signal.

Took out fuse for the radio, inside engine compartment, and went back to normal.

Anyone experience this.
