Radio has no sound
Removed radio,checked (all) fuses back of radio and fuse boxes (radio & sound). Didnt work unplugged wire harness , re plugged in. Radio now works...
Entered radio Code and bam.. power and all display works.... BUT
NO SOUND! IS that PAR for the course or what?
CD changer & cassette works... volume shows up & down.. Staion are displayed but no sound at all.
Snipped yellow/black wire CTEL (TEL mute wire) via another tech post... still no sound... Has to be something simple I would think
Any suggestions?

Found Solution to "No Sound" on radio
in the 99 e320 - Bose system - there is a fuse on the side of the cd changer/amp.
How To fix or check
Check fuses under seat for "Radio &* Sound System"
if fuses are good then follow these steps.
1. -Unscrew the 3 phillips head screws to remove cd changer/amp unit.
2. Pull up on the sound system to access unit.
3.- check the 20a fuse is on the side of the amp itself.
This was my issue and now resolved. Bose is a great system
