Query: For my Garmin GPS III+

I bought this for my motorcycle handlebars and it works great. You can't put your GPS back quickly into it's carrying case with the bracket on because it blocks your ability to fold away the antenna. But that is it's only drawback. Comes with a "spring spacer" for your batteries to counteract the affect of vibration on those batteries which may cause temporary power fluxes. Highly recommend this accessory for your Garmin II or III+
