I have now replaced my proffesional phone with a 12th generation ULF
(84 10 9 145 007), and it was plug and play.

The voice control worked without any need for programming.

I have only read the 03/2000 user manual, and I have tried all of the vioice commands described in the manual.

But there is a few commands related to navigation, that give no response.
The commands are "help navigation" and "navigation" wich is supposed to start navigation to a new destination, "new route" to enter new destination.
All other commands work flawlessly, including other nav commands

Does anybody know if any commands is altered, or not applicable anymore?

I cant get this information annonced by the system since it do not respond to "help navigation". There is no responce at all from the commands mentioned above, not even "sorry"
