how do you get the rds feature to work?
Not sure about RDS (I thought it was a Euro-Spec only thing but it might be on the 211) but as far as rewinding/ff-ing a CD, I don't think you can do that from the steering wheel controls. That can only be done by the headunit. As far as the buttons only switching to presets, I think that's a configurable option in your multifunction display - you just have to choose the options that says tune by preset.
also, as I recall from previous posts, the head unit does not have RDS. MB is way behind on head unit and radio technology.
you live in NJ I see. If you don't get text with 104.3 FM from NYC, it doesn't work.
No go on the RDS. Surprising that it doesn't have it, but I have found that many of the NY stations don't broadcast it anyway.
The presets thing has been discussed a lot, and it personally does not make any sense the way it is right now.
