Confidence.....I think not!
“Acquiring Signal” is displayed for the entire ignition cycle after starting the vehicle and/or bleed through of satellite radio audio into your phone call while using the in vehicle hands free phone system.
SDARS control unit, if part # is A220 820 17 97 Q05 or lower replace. If higher contact the Enhanced Diagnostic Assistance Center (EDAC). Satellite Radio Control Unit (USA) Part # B6 783 0085. This DTB may have been revised since APR05 nevertheless reference it as your starting point.?
He then goes on to 'It is supposed to mounted on the trunk'. I am stunned and the only thing I can say is 'Well, it is mounted like that by MB'. He looks at it again and goes 'Hmmm...'And this is the guy that will be takeing care of my baby!!

Anyway, the service rep and the tech agrees to order the part and set up an appointment for next week. We'll see what happens.
He then goes on to 'It is supposed to (be) mounted on the trunk'. I am stunned and the only thing I can say is 'Well, it is mounted like that by MB'. He looks at it again and goes 'Hmmm...'I am not sure that I agree with you when you say that satellite is not ready for prime time. I think it is more MB implementation that is not ready.
Also I don't know if the color matched small satellite antenna in the pic you specify should rightly be refered to as a puck. Its a very modern, typical Satellite Antenna. The one on my car (& the one other guys had their dealers hide under the rear package shelf instead of on the trunk lid like mine, is the one we refer to as a puck. (Its flat black and the size of a Microsoft Mouse, and LOOKS like a Hockey Puck) I accepted it because thats all they had in March '04, but, one look at it and you had to know MB has no clue when it comes to electronics. My Satellite radio works, but does suffer from more drop outs than any of my friends factory XM or Sirius Radios. even with my puck on the trunk. I've also nioticed that my Son's Honda Accord Coupe recovers from a seldom heard dropout & resumes play faster than my Sirius, AND it seems to have a longer buffer before it will drop out to boot.

On the ML, they have integrated the antennas under a fiberglass shield on the top of the rear liftgate. Since this is my first foray in to Sat radio, I thought it was normal that it would drop out so often, and always wondered why they didn't have more of a buffer built in. I have a few bridges I pass under that I already know I will lose signal, even if I'm only under the bridge for 1-2 seconds.
But I have the damn intermittant "Acquiring Signal/No Signal" display when I start the car... even though the satellite radio IS playing.

I don't know if there is a newer rev of the unit from when others had it replaced but it is working in my car. If others still have the same problem it might be worth going back to the dealer and have them have another go at it.
Details are here. This is on how to retrofit satellite but it also shows you how to get to the SDARS unit.


Folks generally come onto a forum to moan\complain and at times they have every right to do so. I just find it sad that when good experiences are documented the 'moaning brigade' don't accept that possibly not ALL experiences are similar to their own? Not all experiences are bad? In my opinion there are good dealers, there are bad dealers, likewise there are good customers and bad. There are those that can communicate their grievances in a way that earns respect, and there are those that might not excel in this area? I am NOT pointing a finger here. I am merely suggesting that not ALL 211's are defective, and not ALL 211's have ongoing problems.
The mirror sometimes holds the answer!

XM vs Sirius
XM is better signal wise
Sirius drops a lot.
I worked in the car audio field as a sales person and installer for 3+ years. MECP certified as well. Anyways, Sirius relies heavily on a very large network of terrestial repeaters( a network of ground relays to ensure you always have signal). Its not very good. Ive done more satelite radio installs then I care to count and many times sirius came back with shady signal.
While I dont want to take ALL the blame away from mercedes, it can only have as good of service as its provider can give.
