All,
Thanks for the comments. I would be curious if anyone has some input on the Zumo 665 GPS unit. I've heard it can be interfaced with the radio and allow you to hear and make calls through the headset. Is that true? I am not so interested in making calls but being able to answer if I get a call (especially if its the wife or someone from work)! Also, I have the stage 1 and screaming eagle pipes on it and while they are ok, I was curious if I did the 255 cams if that would negate any warranty?
