¿ Stock Kenwood Headunit for Mazdaspeed ¿

[MazdaSpeedSter]

Quick question... If I'm trying to plug a MP3 into the stock mazdaspeed headunit (KDC-MP919) I guess is the model #...

This will do it, with the correct adapter (RCA to MP3 player)

cause there's only 1 input... so I need this plug right?

Also, is there a way to go through the menu (Off, Radio am/fm, CD) such as AUX, or whatever the menu is for the MP3 when it's plugged in? Thanks for any help...!

When you plug in the CA-C1AUX you switch the stereo to AUX to listen to your MP3 player. You still need to change tracks/playlists using the buttons on the MP3 Player. If you have an iPod, the KCA-iP500 can be used instead which allows you to change tracks/playlists from the stereo instead of the player. However the iP500 has gotten mixed reviews from board members and you should do a search for both of these model numbers before buying one.
