What do you mean about "muting for messages as normal and dynamic routing" as you said above?
Thanks,

Dynamic Routing is in the route preferences menu, along with short route, fast route, use motorways, etc. If you don't have it then you will using the Divert option which requires a manual response - I wasn't at all keen on this cos the system would quite happily provide a divert around a 2 minute delay, and then send you on a much longer route with even longer delays. There is no intelligence behind it - with dynamic routing available and enabled, the system does not present the divert screen as it is all automatic.
It was only introduced on the X5 late 2005, so I guess you won't have it on a 2004 M3.
I replaced my early 2004 BM54 with a late 2005 BM54 and the dynamic routing option appeared. It's strange that it is a radio tuner upgrade required and not a new NAV unit, but that's how VDO have implemented the solution. I personally would have thought that as long as you can get TMC, then how the NAV software handles the traffic scenarios is down to the MKIV, but apparently not.
I got my new BM54 from ebay for about £340, but they can be cheaper if you get an older unit, but you must make sure that the version you buy supports dynamic routing.
Oh, and don't downgrade the OS (V27 - V26, etc.) or the ETA goes screwy and the dynamic routing cannot work without a recode.
My NAV is used primarily for traffic avoidance - I know my way to work (most mornings anyway) but it's a long, very busy journey with multiple opportunites for delays. I like the idea that I'm getting the quickest possible route at all times , even though it might not necessarily always be true! Some of the TMC data is a little 'suspect' to say the least.
