What is the best way to hook up an external audio device? I have been using radio transmitter for about a year, with sub par signal. It died couple of days ago, so I have an incentive to mess around with stereo system. Is there a plug'n'play kit I can purchase? What is the installation level of difficulty?

Thank you.

 

Just installed this recently.
USA Spec Ipod Interface

It has both the iPod adaptor and the AUX input. It plugs into the port the external CD changer would plug into. Works great and with the iPod attached allows me to control the tracks with the steering wheel controls.

Installation was easy, remove the console and dash panels around the radio, plug one end into the back of the radio and you're done.

 

Thanks for the info!
