I have a 99 E300TD with the Bose stereo/casette unit. (a US model) I would like to play CDs and know I can easily add a CD changer in the trunk. But I would also like to use a CD play in the dash so I or a passenger can handily insert a CD without stopping the car, opening the truck, etc. I have seen some MB Audio 10 CD units that handily replace my current unit. Is there any reason I should leave my OEM unit in place and try to install a CD player/changer of some sort in the dash behind the flip-up door? Right now this is a little storage area and other W210s have a phone there. If so, any suggestions? Any that work with CDs I copied or compiled? Do I need to have a professional install it or can I do this myself? Thanks
Maybe I'm not reading the question correctly. Are you asking if you should replace the head unit (which would require a new CD changer if you still wanted one) or just add the CD changer inside the cab?
There's no real reason you can't put the changer in the cab, provided there's room for it. Just make sure it's not at an angle that would cause problems.
As for installing it, please don't take this too harshly, but it's one of those situations that if you have to ask, you likely shouldn't try it yourself. Custom jobs never go as easy as they seem.
I wasn't very clear. I know I can add a CD changer in the trunk. But I was thinking that instead of a trunk CD changer perhaps there is some sort of CD player or changer I could install in the exta slot in the dash (the one that is covered by a door), and which would work in conjunction with my OEM unit. I think that is really the main question.
because your head unit is D2B fiber optic, there is less than a handful of CD
changers which will coexist with the system.

none of these will fit a DIN slot as they are waaaay longer by almost 2x. I pulled
out the Audio 30, replaced with Audio 10 (1 min install and activate) and $300
poorer. i still have trunk changer use. drawback: w/o the audio cassette player,
you've just made it more difficult to adapt MP3 or AUX IN to your system. instead of
a few dollars, it'll now cost you upwards of $200 to add this port
Thanks. Audio 10 definitely sounds like the way to go! I have no plans for MP3 or Aux In, and my small collection of nice casette tapes, all recorded years ago and which have been gathering dust since I last had either a casette deck or a car that could play them, will probably go into a time capsule. Can I switch the Audio 30 for the 10 myself? I understand two little tools are needed. Do I have to do anything about security measures, alarms, etc to get the unit to work once it is installed--apart from entering the unit's code? I read somewhere that these units can be pretty fussy about the CDs they will agree to play. Will they play copied CDs without any trouble? (The wife and I buy commercially recorded CDs for the home and copy them for our cars; I also figure on compiling a CD or two with some of my favorites)
swap out takes 1 min. if you're slow and methodical, 5 mins. re-entering the radio
code takes 15 secs. making radio removal keys 15-30 mins. buying them online,
a week or two. buying radio removal keys from local dealer....i dunno, an hr?
