I have a '94 S350D, W140 series. How do I remove the radio?

 

the w 140 comes with his own system amp is in the trunk and everything but basicaly just pull it out revireing is also simple even it looks like a lot of wires. it all comes down to left and right if you wana reinstall a new one but remember this radio controlls the cd player in the back to .i simply disconected it . and installed a new one with a usb input.

 

Look on ebay, Search "mercedes radio tool". They cost a few bucks. If you have a dealer close by, they sell them for only a little more.
