For around $36 and 15mins of your install time, you can add an ipod input cable to your stock headunit.
Get your Mitsubishi dealer to order you the cable (part no: MZ360135EX "aux cable").
Once you have the cable in your hand, you're ready to install!
You need to remove the headunit, and possibly the plastic surround if the cables behind aren't long enough (like mine weren't). You can release the headunit by poking in a thin rod (like a nail or pop-rivet) into the 4 small holes on the front...
The plastic surround is held in with clips along the top, and one screw on the bottom RHS...
Remove the two connectors, earth cable and aerial from the rear of the headunit. The black, red & white wires from the ipod cable go in the back of the white 14-pin plug as per the instructions that come with it - they slot in and lock very easily.
I routed the cable into the glovebox, but you could bring it out under the ashtray if you want. I have since cut the cable and installed a 3.5mm headphone socket in the dash, so when not listening to the iPod, there is no cable floating around
Now carefully put it all back together and you are good to go!! Plug the cable to the headphone jack of your ipod and choose your songs normally. To listen to the ipod through the speakers, press and hold the CD button until AUX appears in the top dash display..
The volume on the ipod AND the headunit volume both work, so you will have to fine-tune both levels until you are happy...
ENJOY!!!
