So as luck would have it I am thinking of adding three enahancements to my 04' RA. First one is a Garmin nuvi 660 and, the second is a new radar detector (since mine died a while back). I am thinking of mounting the nuvi in the bottom-center of the dash and the radar detector on the left-drivers side just off the pillar. Is there any good examples of how to tap or run new power to these two locations?
