No, I understand that. I'm asking how you're able to control the factory system as you say the factory controls work with the AM FM radio? If you have installed a new amp, and I'm assuming you then have the new amp powering the speakers instead of the OEM amp, and then you change volumes with your phone, where does the factory controls come into play? How do you have the factory system tied into it? Are you using the speaker outputs of the OEM system to plug into the speaker level inputs? And if so, it seems to sound alright?
