No SOS yellow light

Does anyone know of a fix or work around for the "yellow color No SOS" light? It has a phone symbol with a diagonal line through it.

Anything on the Most Bus can cause an SOS failure.
Including TCU/Mulf module Sat module and Logic 7 amp
if you have Logic 7 .
Do you have sound?
Do you have Logic 7?
What you have will depend on the year of the car and the options it came
with you need to list those to get and intelligent answer.

You still haven't listed your model year
your head unit type
and what the sound system and options are.
To find out which option were installed in your car put the vin in at the following site.
option in the 6xx range indicate which sound system and options are installed.

Usually the lack of sound in a Logic 7 system means the amp has gone
bad due to water in the amp area.
Recent heavy rains could be a clue.

Not having sound with an SOS light usually indicates more than an SOS problem
it may not be the problem at all.
