I'm trying to install an aux cable to my mitsubishi galant 2008

I'm trying to install an aux cable to my mitsubishi galant 2008. I recently
learned that holding down the CD button is a good way to check if your car is
aux capable. I did that but nothing came up, can i install a new radio that is
aux capable? or is my car in general not capable?

I checked the box and i saw that the pin all the way at the corner was 10 pin
connector. I have an aux cable that has a red, white, and black wire.

Thanks
