i have a startac 7760 and what i have found is that you can get the RJ-45 to the DB25 connection - it is easy using the above links. but i can't find the microphone or speakers (of course in the PIN's of the DB25). A german TT-owner has explained that with the Concert radio and bose systems both door speakers are used for the phone. Also the microphone seems to be in the roof over the back mirror.
ANY IDEA?????? on how to locate the microphone and speakers on the DB24.
Using the above links you can find easy the 12V power.
