For those with the OEM Navi.....
Here is a brief background. I purchased a COMAND (MM) unit to change my Audio 20. I got a European unit from Ebay UK. When I installed the unit I changed the DVD region to 1 in order to watch US DVDs though the engineer menu; I left the market setting on ECE (being JAP/ECE/US the three options) because the radio stations are displayed much better in ECE. No surprise, the unit came with the Euro maps; so I got the US map update DVD and updated my maps…
YES, I have just confirmed you can update a Euro COMAND to US with the update DVD.
Anyways, after updating the maps, the navi would show my correct position on the map and the street name, but it would not let me input an address; it would just say “Function not available at this moment”. So I remembered the market setting on the engineer menu and went back and changed it to US.
Now the navigation is working fine, or so I assume. Here are my questions:
When I changed the market setting from ECE to US I lost several features:
Under navigation mode I had the option to chose from shortest to fastest, and then a list of “avoidable” items. Now, I only have the list of avoidable items, but I can’t switch from shrortest to fastest anymore.
The other feature I lost was the TMC (traffic messages thing); not that it worked anyways (it said no traffic stations cold be found in the area); but now is not even there (so bye bye to any chances of making it work).
The other difference I quickly noticed from the ECE to US change was that the radio stations used to be displayed with their name over the frequency line, now it is just the numbers.
On top of that, some of the things I noticed about the navi which I would really like to very if they are indeed supposed to be like this:
The directions won’t tell you the street to turn on, just “turn right in x feet” but not the street name.
It is impossible to enter the name of a random business; you have to go though the POI categories, which are very limited (no bars or night clubs for instance), so how do I get to a bar if I only have the name?.
On top of that, the POI system is very annoying and very limited (in terms of the number of business it has).
Is your navigation like this as well?

The US FM radio has a bit different but very similar info as RDS in Europe, W221 models receive traffic info from US FM stations and I don't see why the W204 could not. After all, if you can see the radio station names in text, and sometimes some other info, the traffic data would be transmitted with the same approach.
My guess is that the traffic option has been intentionally dropped from US W204 models (I understand this is the same for MM/Comand as well as for UMI?). It could be licence cost or something else. Many European countries provide traffic info commercially, navi manufacturers have to pay for that option.
