Just received a Garmin Zumo 550 from Ebay. Want to hear MP3's and the British chick give directions. Have the RAM mount for the clutch reservoir. Want to keep the powerlet free for electric clothing, so I need to know where to wire the Garmin, and a recommendation for earbuds/helmet speakers that gives a pleasant audio experience. The bike is an '09 R1200rt. The vast knowledge base here is certain to come up with a great configuration! Thanks to all!
