I've just replaced a Concert II+ with a brand new Symphony II+. The installation went smoothly, the Symphony II+ accepted the code without issue and went through what I presume to be the standard initialisation phase. However, I now need to code it for Bose, Multi-function steering wheel, diesel engine, Avant, etc per the Ross Tech guide and I've been unable to locate it via a borrowed cable and VCDS release 11.11.2 (not beta). I've tried Radio, Sound System and Navigation to no avail - any suggestions..?!
Thanks and best regards,
