Sounds like you should invest in an aftermarket headunit.

But, you should be able to just do both the input and outputs, I'm not sure of the problem you are encountering.
cause in the writeup to do the outputs it ecokains to cut thre wires, while a couple post down it states not to cut the same wires in order to do the input, does anyone have a write up where it explains both togerth? thanks

my question is why not use the tape inputs for aux input? nobody ever uses tapes anymore... so why have it have its own input when you can bypass and create your own im sure you have to play with the unit to trigger that there is a tape in the unit, and also disable the motors as from what i read in general those create noise and since you really do not have tape in there you do not need them to function.

its not too much trouble when you know exactly were to solder what to disconnect etc... i might do it :D as i really do not want to have extra other switches when im using something that is stock and using something like tape which is never being used... heck you might even route the CD channels which i believe is also 4.0? meaning for your carPC you could have a 4.0 setup ;) which would be great for movies and surround sound with a good sound card :cool:

I just don’t want to mess with the CD changer when its all good and still useful :)

this could be though an option for those who's cd changer got screwed up and does not work no more :)

Hello!

i modify the Lexus stock radio with a "TAPE IN"

You can with this modification the signal from a mp3 player or some other player with your Lexus Radio. Only you need a good audio cassette for noiseless tape function.

for this function, i open the line between the tape und the source-switch IC on the board. i solder a audio cable on the capacitor and bridge the restistors for more volume for the TAPE IN.

You can modify each radio from the IS, with or without internal amplifier. her pics from the electronic board

sorry, no more pics from this modification on this board

you can use the original capacitor for this modificaton. on this picture i testet the first time with other caps.

Radios with external amplifier have a little other board, but is not difficult to find the right caps und resistors.

---update----
I see i was looking at wrong connector diagram looking at the amp one which has each speaker out, but the CD outputs are only L/R :/ there is no indvidual channels for each speaker set, the amp splits the channels, nevermind then...

hmm what i was going to do was short the switch and cut the motors and other function of the tape so you dont have to hear it, since nobody will ever use the tape, its also possible to use another switch or simple 1/8" norm closed and when you plug in 1/8" its open and you get the sound going in from your connection etc...

If you are looking for a really good plug and play solution you should read this thread . Just scroll a little bit down in this board

my.IS - Lexus IS Forum > 1st-Gen IS300 > Mobiletronics >


http://my.is/forums/f103/ipod-control-solution-oem-stereo-1st-gen-is300-200-finally-found-plugn-play-347712/


The GromAudio iPod interface is cheap, easy to install (plug 'n play in 20 Minutes), keeps the stock design, sounds great, charge your iPod while connected and allows you to control your iPod via the stock stereo buttons :)

Just read through the thread up to the end. There are lots of lex drivers who had installed this thing already successfully!

Best Regards from Berlin - Germany

Sonnet

P.S. The best thing is, this solution needs no modification of your head unit, no welding and the tape is still working (for all old school enthusiasts :cool: )

Help!

Update: below issue has been "corrected".

I followed the top instructions and a couple issues came up:

1) The CD player stopped working. It wouldn't recognize the cds inside the dash. I had to open up the cd player to get my cds out.

2) There's no sound if I plug in the smaller molex plug on the back of the cd player. If I unplug it, the radio would have sound.

Anyone has any clue where I screwed it up?

Thanks!

Your CD player may have coincidentally decided to go out during this mod (also the added vibrations from removal/installation might have caused this). Sorry to hear your troubles.

I have a 2002. Yeah, I noticed that the CD player have behaved weird occasionally.

However, I found my mistake. I played around with the installation a bit more tonight, and found out that the CD player is actually working again after I took all the cds out and put new cds in. The problem with the smaller molex plug behind the cd player is a none-issue. My car doesn't have that plug as shown in the pictures above. So everything works now, and I actually have an alternative method of switching the audio to aux than above. :)

CHEAPEST Aux-in MOD EVERRRR!!

I've wanted to do the aux-in mod for the longest time, and I had some alternative ideas of my own. I finally found time last weekend to work on it. With a little trial and error, I got it working!!

This is cheaper and quicker than other aux-in mods mostly because you don't have to spend or do much for the aux-in switch part. The idea uses a RCA splitter cable to "splice" into the RCA input, then use a CD with a blank track playing while playing your MP3 device.

Here's a quick run down. You will need to get the following audio cables asides from the RCA plugs mentioned in the original post.

1 splitter RCA input cable - shown here from end to end


2 female RCA plug adapter + 1 stereo to RCA converter cable (these will be used to connect your MP3 player to the splitter cable above.


Do the mod as mentioned BUT follow "drinkmalk's" advice as follows:
drinkmalk said:
- In step #6, DO NOT cut the brown or yellow wires, only cut the white, red, green, and black

- Skip step #7

- Step #8, now you should have 4 cut wires (8 leads total, 4 coming from HU, 4 going to AMP), white(L+), red(L-), green(R+), black(R-). Solder them to RCA connectors if you want, the positives leads being the inner leads of the RCA and the negative being the outer shielding. So, to spell it out, white and green goto the inner leads of each RCA, red and black goto the outter leads of each RCA.
After the RCA plugs are installed, just add in the splitter cable, and you're done.


Now, make a CD with a blank track on it. If you find this difficult, I guess this alternative is not for you.


Put the CD in "Repeat" while you're playing the mp3 player.


Here it is... My MP3 player plugging in and playing with the blank CD playing the blank track on the background.
Since it's a blank track, there's no interference with the MP3's input.


Now, I do find that I will need to unplug the MP3 player when I play the radio or regular CDs. Otherwise, there is a slight distortion in the audio. Playing the mp3 device with the blank cd playing has no distortion in my ear, however.

I know some of you will call this a HACK job, but any mod to the OEM car is a hack job one way or the other. I sacrificed one CD slot and saved me money on a switcher and all the additional works to put in a switcher. It's a worthy sacrifice in my book. :)

So I've been using the Aux In for a few years now, then all of a sudden my switch stopped working. Come to find out there was a short with the "pink" wire for the cigarette lighter so I wasn't getting the 12v I needed to run the switch. I tapped into the "gray" wire that goes to the HU, now when I connect everything back up, the HU makes a noise as if it's cycling through the CD's, but it doesn't turn on. Anyone have an idea what's wrong? Did I just F up my HU?

Oh, and the navigation isn't working either...this day just got better.

So, the LCD doesn't turn on at all? Does the radio make the change CD sound to no end? Have you tried disconnecting the switch from the gray wire and then checking your radio? Have you checked your radio fuses (even though the relay pulls barely any current)?

What's wrong with the Nav?

My switch is finicky at times, but it's the actual POS Radioshack switch, not a short.
