I have a 2001 C240 with stock radio and non-bose system. I was looking to install the Kenwood DNX5120 Radio/CD/Navigation unit. I know it is double the size of the stock radio but I thought I could just removed the tray underneath the radio to allow for space. Has anyone installed one of these double size radios in a C-class without massive modifications. Please help, all input is appreciated. Some pictures would be great also...Thanks!!!
