Stereo & Electronics - New HU- Alpine CDA-105, compatible with my power antenna?

So my new hu will be in tomorrow and I was thinking about my antenna and all. Will it automatically raise and lower with my new radio? Like if turn it on will it stay up and so forth? Is there a special way it has to be connected to the new HU?

Anyone have experience with this?

Alpine's have a wire to connect to our power antenna.
