But yeah, I can read emails, stream Pandora music from the Ipad and it displays the info of the music in the I Drive. Just cant take or make calls, which is anoying LOL.
check your MULF to see if there's any mic wiring on pins 1, 19 and 21. if the slots are empty, most probably your mic is wired to the CIC/CCC directly so you need to run a new set of mic wiring. you may or may not need to buy another mic so i suggest you do the wiring first and test out on the existing mic. if VC and phone calls work then you do not need the additional mic.
i think what had most probably happened is that after coding the BT phone, the VC functions may have been transferred to the MULF instead.
