TMC is transmitted primarily in Europe
You need a TMC enabled CD or DVD from VDO-Dayton
I don't think Navteq offer TMC on their CDs

For the UK you need the second one down here :-

note the TMC/Itis Logo

Your TMC icon is Green when tuned in Red when not and black if there is no service or the CD does not have TMC codes

Most of you BMW guys will have either a BM24 or BM54 radio both usually have dual tuners one tuner automatically locks to the TMC transmitter
In the UK it is Classic FM.

The later BM54 offers muting for messages as normal and dynamic routing.

If you are unlucky enough to have a single tuner Radio then it must remain tuned to the correct station to receive broadcasts but CD or tape can also be used instead.

It is a brilliant system offering look ahead information and on several occasions has provide me with almost an instant voiced warnings of something that can only have happened a few minutes earlier the nav screen automatically switches to provide information on the problem it shows when the last exit will be in miles and you have the option to divert

How can you tell if you have bm54 or bm24?

TMC rocks. If only they would include speed camera's in it...

Hey that's a really good idea! I never thought of that, it would work even better than having them on the DVD, cos they would always be up-to-date. There would be no need for any kit/disk updates - just turn it on via classic fm, etc.

Come on BMW/ITis holdings

The problem is updates with CDs or DVDs only come out every 6 months if they did hold Gatso info you could never be 100% sure about that new one just put up around the corner and static info is useless for mobile camera vans.

Carx offers te ability to use the Nav screen to warn of such devices but again this depends on how uptodate the DB is, the one I use is very out of date and for some reason warns me of a non existent 60MPH camera each time I go over the River Severn!

That's why the TMC would be so good - it's dynamic and up-to-date. ITis holdings could get the DB from someone like roadangel or whoever supplies the db, maybe even the pocketgps team

You could have an extra category in TMC for speedcameras and upon connection the speed cameras download with the rest of the traffic updates. Not sure how well this would work re. performance - there are a LOT of speed cameras in the UK!

Oops yes I forgot The traffic camera codes could be transmitted by the Radio Broadcaster but that would take up a lot more bandwidth and would have to be fairly constant as there are lot more fixed and mobile cameras around than the travel related incidents unless the Nav Comp could cache say 50 miles worth of info

The Nav OS would certainly have to track a lot more objects as well

The whole Nav Comp would probably grind to a halt, it struggles now drawing the maps hence the loss of detail with the latest OS releases.

I would imagine somewhere in a model office or developer land VD0-Dayton Navteq and ITIS holdings have dabbled with it though

Yes - we have some major roadworks on one of the Motorways close to us - I get the warnings on screen (red bordered if they are on my route, grey if not) and the alert screen - Also get the delay flow arrows showing the length and direction of the delay.
