You just need to hardwire it into the bike. My buddy has a valentine one and i forget how he has it mounted inside his windscreen. The kinda fun part is actually hard wiring it tho. Can be done easy tho bro.
its probably not legal, but if you take the radar detector apart and use the internals, post the actual radar part up near your air intake and wire the lights over near your gauge cluster, and wire it into your battery..there will be nothing to find ;)
