I have a fairly new Garmin which I use in my car when needed. But I also have a (much preferred) 2012 red RT and was wondering if there is some sort of mod available to clip it onto bike? I assume that the GPS unit is not waterproof, so would need to account for that too. Also- are you all just running the GPS off battery or have you installed an electrical hookup (if so, what). I could technically use one of the 2 aux ports in the trunk and just use my line, but it would be awkward. Anyone out there with reasonable solutions? Thanks
