Ok had a Zuma 665 installed. Also had to have a interface cable installed so I will not have to use AUX. cable. Well system works just fine with using the radio but if I want to listen to XM only way I can hear it is by using AUX. cable. Anyone have any idea if there is something I am missing. I have read the manual with the Zuma and might as well read the local news paper. Any help would be appriceated before I head back to the dealer.

That's pretty much how it works. XM and MP3's played off of the GPS go to the AUX port.

Believe this is the way it works. If you have the Harley NIM (Navigaion Interface Module) installed it will allow the Zumo GPS direction prompts to interrupt and play through the radio, however, to hear the MP3 or XM function on the Zumo through the radio you have to plug the cable out of the NIM into the AUX input on the front of the radio.

Here is a link to the instructions for the NIM, check page 3 para 6 or 9.

Yes, you have to use the aux jack for the xm radio. Alternative is to have a rear aux wired from the original radio. I just got mine back from Iron Cross Audio for that very thing. BTW they are great to work with.

Man that really burns my butt..... I told them that I didn't care if it directions come through the FM radio I was totally interested in running XM or through the SD card. They told me that I would not need a cable if I bought the module cable stuff. Hell that cost me 170 bucks. Thanks for confirming what I figured out already. Keep the shinny side up.
