I just bought my friend's Z1 and installed it with the XM tuner GEX-P10XMT.

The unit doesn't see the Xm tuner.

I also have an ipod adapter (not Pioneer) that attaches to the XM unit via the IP-Bus inout, and the Z1 doesn't see that either.

The instructions say to not use the power wire harness that came with the XM tuner if you are connecting to IP-Bus, so I didn't.

I was going to use it and try, but thought I would post on here first.

Thanks

I would look at those instructions again. You certainly need to connect the power harness if you want the XM tuner to work.

I did... It's the accessory wire, not the whole power harness that shouldn't be connected.. dOH

XM works. Thanks

Although the ipod adapter I bought from Crutchfield which daisy chains off the XM via IP Bus still does not..

hmmm

?

Connect the power supply!!!
