Credit goes to locomotiveBart on
5series.net, but posting this here since I havent seen anything about it.
This is only for 2006 cars so it won't apply to most people on here. It might depend on your software version, but this worked for my 2006 330i. Not sure what software version my iDrive is.
All you have to do is code all of the following to aktiv in the CAPPL module:
TMC
CA_TMC
TMC_REGIONAL_C
Voila!
I'll add pictures later.
