ICOM Next is a later generation of BMW's Integrated Communication Optical Module hardware. Next A is the main interface between a workshop computer or network and the vehicle; ISTA remains the software used to conduct the service operation.
Hardware
The family guide identifies the Next A diagnostic unit and OBD cable, Next B MOST adapter, Next C legacy vehicle adapter and Next D motorcycle adapter. BMW describes Next A as a protocol converter exchanging data between the tester and vehicle control devices. The guide also documents compatibility with legacy ICOM adapters.
Using and identifying it
Confirm the appropriate diagnostic socket, adapter, cable, software support and interface firmware for the job. A normal fault read and a vehicle programming session may have different requirements. BMW's AOS guide calls for an appropriate external power supply for programming and warns against a wireless link between PC and a J2534 pass-through tool.
The BMW hardware guide contains photographs of the components. Compare the family overview and the earlier A2.
