Can 537 DAB radio be retrofitted to 2007 W221 S500L

television: sure (if I remember my electronics), but the particular problem I have is selectivity, which I suspect isn't much to do with attenuation. If there is a fault, it's the selectivity of the tuner, but I don't expect you can do much with a poorly configured pirate radio transmitter broadcasting about 0.1Mhz away (certainly no FM receivers in the house work well).

If we had the facility to disable the mute circuit then they would work a little better, though with some noise, I find the COMAND antiquated in design and usage.
With the ones in the house if you select mono (I know thats lousy) this turns off the 19khz pilot circuitry that makes all of the hissing on a weak signal.
You have selectivity and sensitivity and you cant have both at the same time, we used to narrow the bandwidth in the IF stages to get good sensitivity, but that gives an impaired frequency response.
The old story though only with a better aerial system, and that goes for house or car

John: Good point. I am told the cancellation car (delivery 'late Nov or early Dec') has already been assembled, and believed this. Is this likely?

They have 'last dates' for spec changes since they get a lot of parts pre-assembled from suppliers

Yes, late Nov delivery car is probably built by now

Alex, the DAB setup has 2 aerials on the S class, one in the fin on top, and one in the antenna pack at top of the rear windscreen - so both of those need changing/adding - the wiring loom is available, but i've yet to find the DAB receiver, or better still a retrofit parts kit (cheaper) - its quite a bit of work as you have to wire it into the fibre optics in the car as-well as drop the headliner at the rear - which is an unpleasant job.

Sorry for the delay, just noticed the post, I think you have just about past the final date. DC_Insider might have more knowledge. I was offered the choice of an early re-order and owning a car is all about having the ideal vehicle. The only reason we buy a new car is so that we spec it to our exact requirements, if this is not happening then perhaps a re-think might be required.
