I OWN A 2010 E 350 S SEDAN. I PURCHASED A USED (OUT OF THE JUNK YARD) AMP FOR THE SOUND SYSTEM (HARMON/KARDON. THE OLD AMP WOULD NOT LET ANY SOUND FROM ANY DEVICE BE HEARD. I COULD WARM IT UP WITH A BLOW DRIER AND IT WOULD WORK FINE. SO COLD MORNING NO SOUND. WARM DAY SOUND.THE AMP I PURCHASED WORKS ON COLD DAYS JUST FINE. THE ONLY PROBLEM I HAVE IS THE SOUND IS NOT AMPLIFIED. THE LOGIC 7 DOES NOT COME ON. I CAN TURN RADIO ALL THE UP AND SOUND IS LOUD JUST NOT MUCH BASS OR AMPLIFICATION.

Not connected right?
or
needs to be programmed(which i doubt)
or
maybe not the right amp?

SAME UNIT JUST DIFFERENT PART NUMBER. 2010- 2011 SAME SOUND SYSTEM. MAYBE A REBOOT? PULL THE FUSES?????

On those cars all the sensors require SCN coding, so I wonder if that might apply to radio parts as well.

I HOPE NOT. $$$$$$$
