Hi, hopefully somebody can help. Bought a 135i 2 weeks ago, 2010 N54 Coupe, originally registered in Japan and was imported in 2013 where it had a CIC conversion, not entirely sure what version but has 3D Maps, doesnt appear to have bluetooth although there is a phone button on the wheel, theres a USB port in the glovebox too. My iphone charges when connected but nothing comes up on the iDrive screen, also downloaded the BMW connect app and could not see a connection. Looked in the boot and looks like they installed the harness for the Combox but never bothered fitting one. Do i just need to get a combox and everything will work? Will i need to code anything afterwards, or perform an iDrive update?
