I am sure the issue have been asked and probably answered before.
Emre has done a mod, but the thread is a total maze...
I was wondering if anyone has any newer data!
I have found this unit from a 2014 991TTS
the unit code is 99164217817 and comes with the
control unit.
is there ANY way on earth I can fit this to my car?
I have the Bose upgrade and would love to keep all functions working, besides wheel buttons which I never use!

 

Search 997.1 TT pcm conversion done and you will find 17 pages of detailed information from esmotor .

 

yeah, and as I mentioned, it is sooooo long and complicated
answer that it is practically impossible to follow all the threads, comments, answers and input from everybody.
I am not trying to avoid doing work and educating myself, and I tried to read it and got lost!
Any help will be very welcome!

 

This my ex car!
