My X3 was built in Sep 2005 but I swapped the standard Business Radio for a more recent Nav CID control radio that came via ebay from a crashed US Z4. Build date for new radio is 01/2006. I used the radio service menu to swap over from US to Europe and to turn on RDS etc. All seems fine with this - no problems with FM, TP, RDS, AM etc - all ok. I suspect this is another software coding issue - perhaps the radio wasn't updated when my Mk4 was coded after the nav retrofit. I'll check with dealer.

Thanks for your help.

The US radio is a BM53 (Europe is BM54), maybe Dynamic Route is not supported on that as they don't have TMC. There are also some other differences in the way it works. For example, do you get a list of CD preset numbers (P1:CD1, P2:CD2 etc.) when playing from a CD Changer, or is the bottom section of the Nav screen blank?

Yep. BM53 doesn't support TMC or dynamic routing.

I'm not sure the BM53/54 differences apply to Z4/X3's - I may be wrong but my radio supports TMC fine. For example, if plan a route around the M25 or to Heathrow T1, I immediately see hold-ups and missing lanes and the Nav warns me of this, and reroutes if the delay warrants a new route. It may well be doing this automatically en-route (I haven't yet experienced this but wife claims it works ok) which makes this dynamic route option unnecessary anyway ?

Looking at realoem, the Z4/X3 CID (central info display) controller part (the CD/MD radio) numbers seem the same irrespective of what country you're in. I don't have a CD changer, I use an icelink plus system instead - this works fine with the radio. The radio only has single tuner though - as soon as I switch to Radio 2, (from CD, Icelink) the TMC icon goes from Green to Red as Classic FM is no longer available.

What I find really frustrating in the UK is the total lack of knowledege within the dealer community and BMW customer service in Bracknell of these features - big thanks to you guys at X3/5world - this really is the only place to get accurate info regarding these nav systems.

Thats a very good point. The X3 and Z4 Nav systems, although still I-Bus based are a little bit different from those found in the X5, E46, E38 and E39. You are indeed correct that realoem states the same part # for USA and European cars. Actually the fact that the radio has a single tuner in it, now doesn't surprise me that its the same part # for Europe and the USA. Have you ever checked the service menu for this system. Perhaps setting the "area" determines if TMC features are enabled/disabled in the radio itself. Obviously the NAV computer would also need to be in Euro mode. Interesting ....

Sorry for resurrecting this old post, but it seems to be a very interesting point about the BM53 radio that might(!) support the TMC.

Since the last post in 2006, it seems that a lot water went under the bridge and the US now may have the TMC broadcast on various radiostations stateside.

I am wondering about the details of this particular hardware setup that has been used here - up to this point it has been accepted that the BM53 will support the Sirius and the ID3 tags and whatnot (in latest firmware) but will NOT support the TMC, and the BM54 will not support Sirius but will support the TMC.

From your post it is evident, that BM53 is supporting the TMC - can you elaborate on this a little bit more?

hoping that you remember the set up, as the chances that you still have the same car are slim to none... lol...

Remeber that for TMC to be any use at all the map disc must contain the TMC codes and the road references that are sent in the TMC messages from the radio. So even if the BM53 did support TMC (which I'm 99% sure it does not) you'd still need a compatible map disc, which is not available.

How would a disk manifest itself if it had the TMC data on it? Is there a separate file with a "TMC" name in it?

As I stand at present time, with the US hardware and the US map disks (I think 2011 or 2012, on 2 DVDs as opposed to only single DVD as it used to be before), I only have a greyed out "Traffic Information" option, which is not selectable.

I don't know for sure, but I believe it is encoded into the main map database file.

Hi - I do indeed have the same X3 and it is running just fine !

To be honnest TMC broadcasts in the UK are rarely useful - they're always out of date in my experience and I tend to ignore them and stick to the normal route. Later X3's have a dual tuner radio for sat that continued to monitor TMC broadcasts even while you're listening to another radio station.
