Hey guys, I've had a 2008 Mercedes Benz E350 for 2 years now. The Harmon kardon Logic7 sounded amazing. Until one day my CD changer stopped working while I had CDs inside . I've been reading forums and some people said to remove the fuse for AGW, the CD changer and the radio. I followed the steps took the fuses out, put them back, and at the end the CD changer started working again. But ever since I removed the fuses and put them back into place, my sound has not been the same. I used to get powerful bass from the front speakers, and the subwoofer , and an awesome clear surround sound experience. So much question is do I have to go into engineering mode to get the sound back, or what do I have to do to get the sound? Because I believe that after removing the fuses I must've messed up a component in the radio system that has to be readjusted. I still get sound, but it's not the same as it used to be before I removed the fuses. Sometimes I try, and I put the bass to maximum, and nothing happens.
Guys please help me. Do I have to go into engineering to readjust the sound? When I go into engineering mode the pictures below are all I get.
I know, this is very odd. Yes Logic 7 is turned on. I do feel the difference in the surround sound when I put it on Logic 7. I still get the surround sound experience but it's just that the bass is completely non responsive. Before taking ou the fuses, the front speakers and the subwoofer had amazing bass. After taking out the fuses There's no bass in either the front speakers or the sub.
Disconnect battery for 15 minutes or so then reconnect in an attempt to reset system. If this fails, long shot but basic data in AGW may have been lost in which case you will need someone with MB DAS to diagnose/recode AGW.
I didn't do the process of updating the software yet to regain the data. But what I noticed also that I forgot to mention is that when I turn the car off, the clock keeps going back , or doesn't move forward at all. I have to keep resetting the clock to the normal time in Comand, and I keep getting the wrong time everytime I come back to the car after turning it off. All my sound issues and clock issues started happening after I removed the fuses.
