I'm trying to install a second data link cable on my Data Link-B port as shown below. A google search led me to the chart below.
I already know that our E46 the Data Link-A port is always
used for the CD Changer/Sirius function prewired cable that ends up in the trunk. And the Data Link-B port is usually used for AUX-in function only when adding AUX input to the Radio.
But I want to have two CD Changer data link cables in my car one each off the A and B ports. So one will power my Sirius/CD Changer and the other my USA-Spec Ipod Integration kit.
Will this work or is the picture below the correct code for our Alpine Business CD53 17 pin radios Radio? Is the B-port and AUXiliary Port ONLY? or will it serve as a second CD Changer/Sirius port?
My car already has a BMW Sirius Receiver using Data Link Port-A and I wan't to use Port-B for the USA-Spec Ipod Integration.
This is what I'm trying to do....
