hi, I believe it is possible, but would like to make sure. I have an 03 f150 with the 6 disc cd, and am wondering if what it would take and how hard it would be to install a input like the newer models have. Any help would be great!

 

The 6-disc in-dash changer cannot accept an aux input. I replaced mine with an aftermarket single disc MP3 capable HU with aux input for under $115.

 

Use a PIE adapter & voila. Search the threads,lots of info on this.

 

try an FM Modulator.... thats about the only option. Or get a new deck.

The PIE will not work due to you having the 6-cd changer.

 

Wireless FM modulators suck. Better off just listening to headphones on the MP3 player. Wired is an option (Two here) if you really want to keep your OEM HU.

 

just get a new head unit. it makes such a big difference.

 

A new HU meand he loses the OEM look (design/theft risk), loses 6-CD changer, and usually RDS. If you're using stock speakers, an aftermarket HU don't affect sound much. There are tradeoffs.
