You may want to do a search by hitting the search this forum icon.
Then type in "aux" or "ipod" or "input"
Then make sure to switch the search to title only to get specific results.
You have many options.
The blitzsafe, Ipod2car,usaspec, ect.ect.
The main difference in the types are some just allow you to make a simple aux input and the others (like usa spec) in an interface that allows you to use it in different modes and see the song title / playlist on your factory radio.
I bought the USA spec model from the local car audio shop a few weeks ago because I didn’t want to buy it online and wait a week.
It worked pretty good, but I took it back because I think I'll just get an upgraded NAV unit.
