Did I install Sirius incorrectly?
 

Got my BMW sirius system installed. Everything seemed to work well with it. I thought I was still supposed to be able to use my CD changer. Might I have done something incorrectly?

yep, you should be able to use both.

it sounds like you are missing the passthrough cable, see the description here from BSW:

The BSW Sirius Direct system connects to your existing CD Changer connections in your trunk. If you already have a CD changer or other device that uses the CD changer connections, or you intend to add one, you'll need to add this passthrough cable which creates another set of connectors after the Sirius unit.

Thats just it. I got the pass through cable and installed it according to the BMW instructions. The "mode" button just wont pull it up. I will have to check the connections.

Hmm, yea that would be my next place to look, otherwise I would try to unplug the sirius and double check your CD changer is performing normally still without anything new plugged in.. You should be able to get both to work though for sure.
