Car supposedly has an AUX option but I can't find input?

I have a 2006 Honda Accord Sedan. On my radio it has "CD/AUX" and under that is has the XM for Sirius XM. If there's an auxiliary option, where is it? And if it doesn't have one then I will just buy an FM transmitter or something.

Might have to remove the head unit from the dash to find it…

Look around the charging outlet area, sometimes they are even in the armrest section between the 2 seats

Try looking into the middle section if you have a charging point, it's usually located there with japanese cars for some reason.

It does not have one. Audio shops like crutchfield sell adapters you can install. The back of the head unit will have a socket to plug that in

Use the instruction booklet

You need to install an adapter for an aux port in a 2006 Accord. Just like my 1998 Corolla has a button for CD/AUX, that is in place to control an optional OEM CD player that would plug in theback of the stereo. There are lots of youtubes on installing aux and bluetooth adapters inthe '06 Accord. Take your time. It was easier for me to install an FM modulator in my car.
