Ok, i gave in and ordered the correct harness and the antenna adaptor and the install kit.
Now, id like to keep the ability of turning the radio on with the car off. Like the factory radio. But i also want the radio to still cut off with the ignition switch... like the factory radio. Is that a factory radio specific feature? Or can i wire it up to do the same?
