Thanks KiwiJochen, RichardP1 for your answers.

I now understand Dynamic Routing. I have got TMC and TP working in my July 03 MkIV and from time to time I am asked whether I would like to re-route around heavy traffic areas, just as you said. I hardly ever accept the offer though. I don’t know whether I would be happy to be re-routed without my consent or without knowledge of the reasons why, of the extra distance or time involved.

I feel there must be a sequence for TV in motion: Some dealers in my country are known to be performing such a modification via their DIS system, some times for an extravagant price. I hear there is some obscure option in the DIS system menu that performs the task, although it would seem this is not very well known by all dealers. I guess monitoring the I-Bus while performing the task would provide the hex sequence. Any takers?

As for the Off Road Navigation option, what I was actually looking forward was the possibility to set a destination by means of latitude and longitude alone. No chance then, I guess.

Thanks
