If you expect it to be useful on the bike, then you need either an intercom hookup, a Radar Screamer, or a HARD LED system. The V1's volume alone will get drowned out at higher speeds, which is when you need to be able to hear it clearly . . .
And you will need to deal with rain. Your options are:
1) Never ride in the rain, ever.
2) Remove the V1 and stow it someplace safe (a velcro mount is handy here, which also gives you the ability to remove and pocket the detector in between when it goes off and the nice officer pulls you over).
3) Use a sandwich baggie, or one of those elasticized bowl covers which are easy to put on.
3) Get a clear, custom-molded Radar Cover from LegalSpeeding.com.
4) Get a Radar Box from LegalSpeeding.com. This box is made by Hoon Hardware who used to make a locking shelf setup for the LT as well, though I don't think that is in production any longer.
5) Make your own cover box, as some here have done.
And always remember, a radar detector gives you additional information about the road ahead, but doesn't give you a free pass.
