I installed my HeadUnit Saturday. Brand new Sony CDXCA400. Well the problem I am having is that everytime I turn the car off I lose all my presets and clock goes back to 1:00. When we hooked up the Power Ignition wire from the stereo to the Power Ignition wire from the car and the Battery wire from the stereo to the Battery wire from the car the head unit would not come on at all. So I had to plug the Stereo Battery wire and the Stereo Ignition wire to the car’s Power Ignition wire. The head unit comes on but my presets will go away when I shut the car off.
There is one wire from the stereo not plugged into anything and that is the power antenna. But I have a 5th gen dx that doesn’t have a power antenna.
Am I supposed to have that plugged into something?
O.K. if I run a wire from the battery to the battery wire on the headunit this should solve my problem but will that mean my headunit will run without the key in the acc position, in other words I would manually have to turn it off all the time.
Anyone with wiring knowledge please help.
