Thanks for this writeup, helped me out a lot.

I did find a perfect harness for this type of install. My car is the same as yours' E300D with the becker 1492. Found a harness at Fry's Electronics.
On package is Metra, Turbowire. 70-1786. Says is for Mercedes 94-04 and Land Rover 99-04.
The wire locations and their usage exactly match the factory Mercedes harness.

Thanks Jayb. That is awesome. I'll have to pick one up myself for the next time I have an hour to blow on changing out the wiring!

Thanks for the post. I am in the middle of doing almost the same install (MEX BT2800) on my 95 E320 and have a different question. Does the sleeve fit into your dash or do you have to modify the black plastic guide. The sleeve that came with my radio is too big to fit the opening.

I just bought a 1995 E300D and have a head unit sitting around with an AUX-IN. I was planning on buying a stereo wiring harness and dropping it in but everyone over at (another popular MB forum I won't name) said that aftermarket units wouldn't play with the audio system? Have you had any problems with this? Thanks for the write up, before I read this I was going to buy the Grom AUX-in adapter instead of swapping in the newer head unit.

Mine plays fine, pretty sure kickit just hooked his up to existing too.
I'm not happy with my sound, but it's no worse than it was before the new head unit. I'm going to replace everything, speakers and all, but that is going to wait till I get the remote door unlocker installed. Priorities...

Nope. The Sony model I used just worked fine. The antennae works and all of the speakers worked. One of my front speakers was blown so I replaced both, but that had nothing to do with the new head unit.

Sleeve fit on mine, but was super tight. Which you'd want, of course.
But yea, took a lot of wedging to get it in there. That's what she said.

You are correct, I did have to trim a little off the corners of the black plastic guide. I just used a box knife as the plastic is pretty soft.

I just installed a Kenwood into a '95 E320. As was said the sleeve was too large.
I didn't want to go butchering the plastic so i just installed the radio without a sleeve. It wasn't tight but it wasn't loose either. I'll see how it goes and if it doesn't stay put I'll have to do something to make the sleeve fit.
