I called Honda to ask if it was possible to install the factory nav unit on a non-nav car and they told me they couldn't do it because they had no tech specs on doing the conversion. So for anyone that has done headunit work on this car, does anyone know how difficult it would be to simply buy the factory nav unit and swap out the non-nav headunit for it? That way I could keep the steering wheel controls and iMid functions. I dont see how it would be that hard but Honda can't answer my question about it. Thanks to anyone that can help!
