I've looked through the forums and although come across similar posts have been unable to find one that works for my vehicle - a Mercedes CLK W208 Cabriolet Avantgarde 2002. I am trying to remove the COMAND unit with the intention of replacing with a Pioneer unit. I had left the car with my local Halfords for them to remove and replace with the new unit but with no success. In fact you will see from the photo the marks left in the trim following their attempts. I am now trying to understand why the unit will not budge. I purchased a pair of extracting keys, including small hole in the key shaft, but now the keys are just locked inplace and no matter how much pull the unit ( or keys ) will not move. I saw on one similar post that a pair of screws were to be removed but I have been unable to locate any screws or similar but sure this is the issue. Can anyone provide any guidance please on how I can remove this unit? Thank you in advance. Graeme PS. The attachment is a photo of the COMAND unit in situ.
