Any way possible to mod in an Aux jack

Anybody have any idea if it's possible or how difficult it would be to add an Aux jack to the 2019 accord's sound system? Could it be as simple as splicing a wire in the stereo unit?

Any luck on figuring this out?
Just today I was thinking about how badly I needed it. My charger started jiggling in and out of my phone and it kept disconnecting. If only I had an aux wire things would be so, so much easier.
That's harder to do than you think it should be. Even with an old school radio, you needed to figure out the amp circuits to add the AUX at the right level. Headphone jacks are designed to work into low impedance earphones, so if you attach them to a high impedance amp you'll get poor bass response. Even if you attach it at the correct spot, I've never been able to solder the connection reliably. (Your soldering skills may be better than mine.) It's even worse not that you have to figure out the circuits in a computer in the dashboard. I've given up trying all that stuff.

Cleaning the charging port on your phone and finding a way to hold it that doesn't strain the connection is your best bet. Or maybe look for a Chinese or European spec Honda that has an AUX and buy the part and try it. Good luck.

So you have done it before on a 10th gen accord?
My understanding is that the amp only has a digital input, so I'm not even entirely sure if it is possible to add any type of aux input without replacing the amp entirely.

I wouldn't even consider doing this to a new Accord. The chance of smoking the whole system is too high for me. I've added AUX to an 2004 Toyota radio, it worked for about a week before the connections failed.

The amp must have an analog output, so you should be able to add an AUX, maybe with an analog pre-amp, if you could identify the circuits between the DAC and the amp. All that is way beyond my skill set. YMMV.

Have you tried bluetooth?

Thanks, once I can figure out the model amp it has I guess I can investigate further.

I loathe the sound quality of bluetooth audio.
I keep thinking that someone must make a USB device that will take analog audio and feed it via USB as though it were an iPod or the like (even if it is otherwise dumb since it couldn't control playback in any way). I suppose that means it would need to convert analog to digital, but at least it could draw power from the USB port.
