Buy a SONY unit! Mine automatically brings down the antenna when in CD mode. You may want to check if your unit has this capability or not. If your running the trigger wire from the HU it will control the whole operation.

If anyone was following my follies with the power antenna, it's done! Installed an after market, Harada unit, today. Ironically enough its the same piece as the Ford OEM but with a slightly different wiring set up. Works like a charm!
