Hi, I have a 98 Honda Civic LX with just a standard radio and I'm looking to hook up a CD player to this for now, before I can actually replace the entire receiver.
Does anyone know if this model has a hidden aux input anywhere? Or any ideas on how I can connect a portable CD player?
thanks
The Civic has no such option, nor does any OEM radio that I know of. The only way you can hook up a portable to run off the OEM system is to buy one of those cassette adaptors
The best thing to do is if you want to keep the OEM stereo is to purchase a FM modulator changer or if keeping the OEM system is not a priority, then you can buy a new indash CD player. They're cheap now ...under $ 150 for a decent one from Alpine, Pioneer or Panasonic 
Good luck.

There are some OEM units that have AUX inputs - actually they are CD changer inputs. They want to sell you THEIR (usually overpriced

) CD changer. I was able to reverse engineer my factory head unit (MAZDA Protege) and use the CD changer input as a Line-IN for a MP3 player! Check out my page. I'm sure it's different for your car, but you may enjoy the info, or find a way to adapt it for your car.
(sorry - I have no specific help for your car)
