Great info >>

Now what I learned is:
1)The HU signal (HIFI option) is Balanced.
2) The HU use twisted-pair to transimit signal per channel.

But it really confused me, because balanced signal need 3 wires. How BMW use 2 wires to make balanced signal. I sent a mail to Larry to inqurie the balanced input capability of bit one, here is what he said:

"If it is 2 wires then it is NOT balanced as that does take 3 wires to be balanced. If so , no sweat just solder up some RCA s and rock and roll."
