03 E500 Bluetooth upgrade

An important point is what you need....by the terminology I have seen...... (I may have "adapter" and "replacer" back to front, but you'lll figure out what I mean.)
a) an ADAPTER or
b) a REPLACER
An ADAPTER is for if you already have a cradle that a phone fits in, in your armrest console. It looks like a phone and has no cable ("tail")
A REPLACER is for if you do not have a cradle, but do have the car otherwise-prewired. It also looks like a phone and does have a cable ("tail") that connects into the wiring. It does not fit into a cradle, of course, because there is none in the car.
My 2004 E320 had the cradle and I bought an ADAPTER like this:

It plugged in easily into the cradle, was simple to configure and works fine, with an occassional need (every few weeks) to unplug it and repower it on.
So, do you have a phone cradle already?

If the car already has a cradle because the original owner spent the necessary bucks, then the adaptor I linked to is sufficient. I use it quite successfully. My e320 was built in August 2003.
The only thing I don't get is SMS messages through the car. I have heard that this is because many phones don't support SMS text over bluetooth. But I wouldn't know for sure on that angle and it was not a key issue for me.

So, it would seem it need not affect BT-based telephony and you can get the error removed.
