I have an E240. UK-spec 2002. <br> <br> Under the radio (MB CD Audio 10). There is a storage space. Is this useable as a second standard DIN slot?<br> <br> Looks about the right size. I want to keep the standard CD-radio.<br> <br> But want to add a Blaupunkt RN149 just for the Sat-Nav functions. <br> <br> Is there the appropriate wiring harness' behind this panel? I think for Sat-Nav it needs ...<br> <br> Power? <br> Speakers? <br> Speedo pulse? <br> Reverse-light? <br> <br> And I will probably have to wire the GPS antenna myself.<br> <br> My idea is to hide the Sat-Nav behind the panel. So I can set the destination. Fold down the wood panel, and just listen to the voice guidance. Discrete!<br> <br> Possible? Or is it a lot of work? Ideas?<br> <br> Thanks.
