longer sizes available.

Since the Z1/Z2 doesn't come with an AUX port, you can plug it into the audio portion of the Video input. And if you really want to get fancy, you can buy an IP-BUS AUX input. $14 on Amazon but out of stock. Available many places. $4 on eBay (or make your own

They sell a direct fm cable, plugs into your antenna. It is $32 at best buy.

I have the sportster 5 and understand why you want it over the sirius for pioneer, but I rarely used the rewind features anyway.. So it has been in my trunk for about a month, lol. I have xm on my z2, about to get the sirius pioneer unit so I actually use my subscription.

part # CD-RB10, it plugs into the ip-bus connector, then you'll need the 3.5 to rca adapter as mentioned above.
