My "One Stop Electronics" cable doesn't work with the E70 because the vehicle doesn't have the #1 ignition terminal in the diagnostic connector. I ordered another K+D CAN cable hoping that at the price they are now they have that figured out. If that doesn't work then I will probably mod the second cable with a switch to simulate the ignition or get an ICOM unit. I imagine the ICOM parses the data stream to tell if the ignition has been switched on?
