Well, I guess I'm not alone also got a 550 for Christmas.
CAP, noticed in your pics, did you use the short, medium or long RAM extension? Also, tell me how you wired it.
I've decided to wire mine by extending my Battery Tender plug up under the tank, and wire a matching plug to the zumo (after shortening the wiring to include the fuse). That way, I can use the same plug to either power my Zumo, or plug to the tender, and can quickly complete remove the Zumo+mount anytime. Thoughts?
Waiting for the 6ft BT extension before going any further...no sense in not getting it right the first time!
