I was wondering if anyone has any schematics of the MFD boards or anything like that. I do not have the service manuals so I don't know if these even exist. The mod of cutting the violet (speed) wire or putting in a switch, or using a lockpick is well documented on here. I found an older post which provided a circuit to intercept the "on-hook" and "off-hook" switches on the steering wheel and essentially flip the switch(break the violet wire) for you (which seems to be the coolest solution I have found). BUT my thought is if we had some idea of what was going on in the MFD then maybe we could see where this speed wire goes. For example if the violet wire connects via the connector on the back of the MFD then branches to different circuits then perhaps you could simply cut the trace on the MFD that goes to the bluetooth circuit and not affect the "5 minutes bars"?!?
