TMC function
 

My 2001 X5 4.4 sport has the 2001 Nav CD ( Mk 3 ) .The TMC doesn't work on the Sat nav.I read that you have to have an up to date version of the Nav CD for the TMC to work.Does it only work with the current version that BMW sells? If not which version could I get away with to get my TMC active. :thumbup:

Since nobody else asked, what's TMC?

Stands for Time Machine Control. It's right next to the flux capacitor. Seriously, I was wondering the same damn thing. Mr. Wizard? You out there?

I cant remember what is stands for but is Traffic .... .... What it does is when you are using the Sat Nav if the TMC is turned on it tells you of any hold ups so you can go around them and not get stuck in traffic !

how do i know if i would have this? sounds pretty useful down here in so cal.

I believe the TMC function is only available in the European market. I'm also not sure what it stands for, but the T definitely stands for Traffic ... perhaps Traffic Monitor Control? :dunno:

It has been out in europe for some time and just been released in the uk.I think the info comes from radio stations If I could work out how to post pics on here I will take some so you can see what you are missing Maybe that is why your cars cost nearly half the price of ours in the uk LOL

it stands for traffic management control, the later nav versions in europe not sure about US receive travel bulletins and update the Nav map with travel delays/accidents if there is one on your route it will flag up a warning and if pos. offer an alternaye route. Works well as long as travel news is up to date. i have come to areas that the nav thinks are blocked only to find it cleared some time ago.

I TMC not in any of the manual the cars come with. I'm no wizard......but it stand for TRAFIC MESSAGE CHANNEL. Works via radio signals in UK.
Hope it helps

You have to have a TMC enabled disk AND a TMC enabled Radio Pack such as the BM54. The 54 has a dual tuner, one of which is dedicated to the station selected as the TMC broadcaster. In the UK, this is Classic FM.

A non-dual tuner radio pack WILL work, but the TMC will only operate if the radio is tuned to the TMC broadcaster.

Not sure if the Mk3 Navi has the TMC facility. Damned useful bit of kit though - like the UK Trafficmaster service on steroids.
