06 professional HU in an 09
I bought a used 335i that came with an aftermarket headunit. OEM radio is long gone, I want to so some coding and I want to be able to go to dealer for some updates.
I bought an oem professional headunit came from an 06 HIFI, can I code it to work or do I need an 09 head unit?
I have installed 06 headunit and radio, cd and sound work, however PDC, door chimes and any other car sounds do not work.
I have a cable and INPA kinda working (I coded out active headrests successfully) Where can I go from here?
My goal: Relocate HU to trunk and use aftermarket headunit 90% of the time, have PDC & Door chimes to work.
I do not have SOS or Assist.
