i am in the process of buying a 2021 honda civic ex. i am one of the ones who still wants a cd player in my vehicle. i have checked with the dealer and they do not offer an option themselves to add a stand alone cd player. i am curious to know if anyone has pertinent information of adding a cd player (i am guessing it would need to be via usb)---it would need to be compatible specifically with a 2021 honda civic ex and also it would need to be able to be integrated into the existing audio system so as to be able to adjust the volume, etc with the steering wheel controls. if anyone knows anything about this, please pm me.
