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?
