So I finished my install yesterday for the most part, until I found out that the CD-IB100II and the GEX-P920XM both use the same IP-BUS connection. The problem is, there is only one IP-BUS connection on the back of the Z1. The manual says if you use the XM NavTraffic tuner you need to have the extension cable the utilizes a different port. But that cable can't be used for the regular XM tuner that I have.

Am I SOL with the tuner that I have? Is the only fix to get the NavTraffic tuner and the extension cable?

No you are not SOL.

The CD-IB100ii has TWO IP-bus ports. One blue 'in' port and one black 'out' port. Plug the XM tuner into the in port of the iPod adaport and then the iPod adaptor into the Z1.

I didn't think of trying that. Was wondering why the Ipod adapter would have an in port.

Thanks

Yah, just daisy-chain them together....de-de-dew!
