GArmin Nuvi install

[JH3]

Anyone wire in a Nuvi to an H3 yet? Trying to get ideas on where to have the wire come up to the Nuvi from the dash and what wire(s) to tap into. Would like to run a wire to the fuse box, but since it is under the hood, it may be more work than it is worth. Would like it to come on and turn off with the ignition rather than using the sockets, which are hot all the time. Any thoughts?
