1stbenz00e55

Greetings Everyone.
Ok woke up this morning and my Radio Now says No CD Changer!!!
Disconnected/reconnected the fiber optic cable as well as all harness heads and still not reading the Changer. When I bought this car I simply swaped the cartridge from my B540i instead of each cd. Could this make a difference? meaning is there something on the OEM six disc cartridge that the Benz is looking for?

Any and All Help is welcomed as i do not intend on spending $$ on replacement...

Thanks

could be the changer is toast.

My nav unit in mine did that after 2weeks of use. Said no Nav. If it was sold with the car new then its under the factory warranty
