Looking into buying a Zumo 660 or 665

[AngryAmish]

I am looking into buying a Zumo 660 or a 665. Difference being the 665 has XM Radio. How loud can we hear the XM radio coming from a GPS ? Can we hear anything ? .... Is there a way to hear the XM through the speakers of the bike ?

Plug an audio cable into the gps and into the aux input on the cassette. You could even do the aux splitter and have the gps connection to the aux inside the fairing.

 

Another good option... BuddyRich cable. If you have a smartphone with bluetooth and a headset, you can even make/receive phone calls !
