Gosh I hope someone can tell me how I can use the XXL 540S on my motorcycle. I don't see an ear plug connection, just the USB jack. When I ride I always have ear buds for the MP3. I heard I could use a Y connector (2 male 1 female) but I don't see a plug other than that USB connection at the bottom. I need the MP3 to be muted when the GPS is talking directions. Any help?
