I have been reading the A/V forums for the past couple hours and still have not been able to find the answer to this question.

Is it possible to connect an mp3 player (not ipod) to an 03 tl with navi and have the information display on the navi screen? I have been looking through all of the navi hacks and have not seen anything about this. If there is a thread out there, can someone point me in the right direction?

Thanks
