I am having my 9500ix professionally hardwired Monday but on my 2007 Audi A6 I had used a 2 amp fuse for the radar detector and kept the original fuse from the home link which was a 5 amp in the top slot of the add a fuse. Make sure you get a good ground otherwise it won't work. I learned that the hard way after 1 hour of figuring out what was wrong I noticed that my ground was bad.
