What is the easiest way to add MP3 capability to a stock 99 gs400? I have a navi unit and don't want to get a new headunit, but want a quick "direct-injection" into my sound system (don't know the term for having a sound file transmitted directly to the speakers without any mediums to travel through).

I thought about getting one of those cassette's that you can plug to a cd player or mp3 player, but the quality sucks.

 

Ipod interface. Look it up. Its a device that is hard wired through the cd player. You can control playlist, tracks, etc. through the stereo display.

 

There's a huge thread on that on the Audio, Electronics section.

 

^^^^ wwhhaaaaaa??? are you serious?! there's a thread committed to just car audio on here? i would have never thunk it.. OP try that section or there's this crazy SEARCH tool on top as well.. It will blow your mind bro'.. GL
