xm/micmutes/gps - getting wired

Ok it is time to get wired. Xm radio install (split the fairing etc) should be a breez thanks to all of you. Hope to have accomplished yet this week. Micmutes not ordered yet but install should be easy. Again thanks to all of you. Great pics and instructions. Then there is this whole gps thing. I have been searching the forum and frankly I am lost. Whats the best install?

Xm and gps via splitter? Not sure I am capable of listening to both at same time. (I like my Roady.)

Gps via Intercom? How would that work with micmutes? Micmutes a must. I don't like amplifying the engine and road noise.

Have a Lowrance GPS purchased from the sporting goods dept at Walmart. Supposed to be water resistant. Has an earplug port. Just not sure how to utilize it with our headsets.

May be I am just in overload here. Afterall I purchased the scoot to get away. Do I really want to know where I am? By the way, I am not intrested in wiring up the phone.

Would defeat the whole purpose!!!!!!!!!

Thanks in advance. This is one teriffic site!
