Subject: OK, I jumped I-bus from TV conn to DSP amp and I have CD sound but no tape, TV, Author: bmw635 : 15597 posts Posted on: 2007-12-05 18:07:07

radio. From what I understand I-bus is more of a communication data/ protocol rather than a "hardwired" signal, so could that be "recoding" will update the protocol so it recognize all installed HW?

Could the I-bus signal/ protocol blocked somehow/ somewhere because:(1) Lowew DSP amp is not coded to NAV? (2)the MK4(May 06) is not coded to VIN? (3)DSP amp didn't get coded to TV? Where is the "main data/ control" that's feeding the I-bus resided (radio, 4:3, MK4, TV, DSP amp)?

I am trying to open couple radio, NAV, amp schematic on X5world.com and all the files with extension.svgz pops up a new browser but seems like it hangs. If anybody have WDS for I-bus in the trunk area (NAV, amp, TV, MK) please email me.

Are these problems can be diagnosed from the GT1? Thanks.
