Problem with Linguatronic retrofit on NTG2.5

[wongl]

I retrofitted two Linguatronic stalks to both my W169 A-Class cars today. One worked straight away, but the second one didn't. Interesting to note that the second unit is missing a Linguatronic menu option in the System menu, so I suspect this NTG 2.5 needs to be coded to enable Linguatronic?

Thing is, I have a Star with developer mode, and although I can see the variant coding on the NTG 2.5, I don't see an option to modify the variant coding on the unit to change its coding. Can anyone suggest how I can do this with Star?

Solved

I managed to solve this problem by coding the head unit to 'activate' Linguatronic using developer mode.
