Sorry for the double post, but maybe this is of some interest fellow Space Star owners.

Is there a safe way to do this with the original Mitsubishi stereo head unit?
As anyone been able to setup a auxiliary input that connects a mp3 player to the original head unit without sacrificing safety and the original head unit functions.

I think this may be possible by finding the audio connections for the CD changer in he back of the stereo head unit and somehow connect a cable (which one?DIN cable?) and trick the head unit into thinking that the mp3 player is in fact a CD changer...
Long shot?Maybe.
I don't have the technical expertise to do this on my own, but I'm willing to try this when I find the right car audio specialist.
In the meantime, do you guys know of any kit, non-do-it-yourself or alternative solution to make this possible?

You can buy a small wireless unit which can be tunned to any unused frequency on the radios FM band. The unit plugs into the cigerette lighter socket for power and has a lead that plugs into the MP3 player. Switch radio on, tune to the unused frequency and you have your MP3 music over the radio.
Units are sold by D-i-c-k Smith model number Z111 and covered by FCC regulations FCC ID R63TWV101. It really is a great little unit, cheap and works well.

Hey! Thanks a lot for the tip. Looks good, I'll try and check out one of these. Some say these fm transmitters cause a significant sound quality loss. That's why I was looking for a cable solution. Nevertheless it looks that I'm going to start using something like this.
Again, thanks!

Uh, yeah, the FM modulator isn't great. I wouldn't buy it, but that's an audiophile's opinion. If you can get a hold of a modulator that you can connect between your antenna and the head unit, it would sound better.
