Well surprise, surprise, and unresponsive ebay seller... I've messaged him twice now asking what's involved in PAYING for him to do this service which he advertises in his ad that he does and no response. Awesome. Where to go from here on figuring this out?

I have a 91 with the tape deck (its a Japanese import if that helps identify it), how to I tell what model it is to know if it has the three prong plug before pulling everything out? Desperately want an aux in but haven't been able to find anything about using the cd changer line etc so this seems like a good route.
Honestly, i couldn't tell you. If you were to take some time out from your day and just check it, and report back here if it's doable, that'd be appreciated. It'd be nice to keep tabs on all the factory radios that this works for.
I had the guy at http://factoryradioservice.com/ install an auxilary jack in my SC400 Nakamichi head unit. Cost me $60 + shipping, but it works pefectly. All you do is put the radio on, and then plug the AUX cable into the port on the front of the HU (or into the cable he'll install from the back of the HU if you prefer), and then plug the other end of the cable into your MP3 player - and BAM, MP3s off your radio.
Well, yes, you don't need to use the exact components i listed. But the reason for servo cable is that it's a direct plug in. And then that AUX jack from radioshack has 3 easily solderable points and a threaded body, so it's very easy to mount on the rear of the radio housing.
Sorry, I forgot about this until I checked my old e-mail account and saw the replies. Anyways here is a picture of the headunit. Car is a Japanese import Toyota Soarer GT-L. Can you identify what headunit this is and if it has that 3 prong connection to wire in an Aux connection? If not I have two interior pieces to replace in the next day or two and can see about pulling the unit out to get a look at the back at the same time. Thanks.
I just did this modification today and it worked out perfectly! My tape deck is broken so I have to use my CD player function to get a dead channel to play through but it operates just the same way.
When I used a standard stereo cable for the aux connection I would get a buzzing feedback signal in the sound system whenever I plugged in my iPhone charger. I would also get a high pitched static whine noise when the engine revved. Unplugging the charger made it go away. This thread describes the same issues and recommends using a ground loop isolator for the audio connection: http://www.clublexus.com/forums/is-f...er-outlet.html
Radio Shack has these for $16. You can get any ground loop isolator you want. They all perform the same function.
And make sure you have whatever adapter accessories you need to go back to a standard 1/8" connection. Some other GLI models are 1/8" on both ends. The Radio Shack model is dual RCA. The gold double-ended connector shown here was actually the wrong size-- bought it by accident. I found a spare one in my toolbox.
And here it is installed in the console. I stuffed it just under where the cupholder goes.
Now your audio should sound perfect and crystal clear regardless of whether you are charging your iPod/iPhone/whatever.
I also found this other ground loop isolator model that offers stereo sound and charging out to a standard iPod/iPhone dock connector. I am trying to find out if the pinouts work for iPhones.
Pieisgude, thank you for discovering this mod in the first place! It's such an easy way to give an otherwise decent stereo system new life. Plus, no need to put a flashy, thief-friendly headunit in the dash just to use an iPod connection
