Thanks to all for your contributions. This actually helped me install a different device in my RX today. I purchased a USA SPEC iPod interface and cable from Crutchfield and mounted it inside my glove box. Now I can charge my Iphone 3G and play my Iphone through my factory Nav unit. It works great.

Thank you TomV and all the other posters who offered advice in this thread. This was very helpful for me and it was nice to see the pics and wiring diagrams. I just got this wired up over the weekend and it works great.

Thank you.

I have the USA Spec too for our Camry. Word of caution, if you but a Gen4 Nano you will have to get a new cable.

I am about to do this to my 2000 RX300, I want to know how important the relay is, and can i do this without it. I looked and wouldent I be able to just splice the two RCA cables in to the output from the cd canger? I would appriciate any responce to this.
Thanks

I have essentially done that (although with mating connectors to insert a custom wiring arrangement without splicing). I only play satellite radio, so it works for me. If you wanted to use other modes, it would be more of a problem maybe. As I recall, you need to have the CD changer playing (silent CDs). I thought about that but elected to have the cassette tape input selected and play a dummy cassette tape. I think one reason was a less annoying display on the screen.

Thanks for the quick reply, I think that i will try this tonight.
Thanks

I tried this process tonight but got mismatching connections out of the cd changer unit on a 1999 RX300. Only 5 wires are coming out of cd changer and the colors are not matching the ones specified in this. Has anybody faced a similar situation like this?

Any response will be appreciated.

I checked my CD changer and the unit is Pioneer cdx-m9186zt (86270-48030). The harness has only 5 wires going in pins 1,6, 8,9,10. It seems 1,6 are for power as when I removed them, it didnt power up but I may be wrong.

bob2200

Please explain what "this" is (i.e., what did you try?). Also please clarify what you mean by "mismatching connections".

vivawafs

Thanks for your help bob2200. Here is what i did.

I took out the passenger side panel and see the cd changer with two sets of harnesses. One is a blue socket with one wire coming out of it (I am guessing here this is the serial line for CD player check by this head sytem.) and the another socket has a harness having 12 input points.

In this thread, the wires were of color white/red/green/black for the R and L output. I didnt see these specifc colors in the wires that were coming out of the cd changer.

By mismatching connections I meant, in this thread the pins were 1,6 and 2,7. In my case nothing is present in 2 and 7.

These are the 5 wires and their pin location that I found:
Pin no. 5: Red with a stripe of white
Pin no. 12: Gray
Pin no. 10: Pin with black strip
Pin no. 9: Grey with red strip
Pin no. 8: Brown

The other pins were empty.

I tried out by splicing the wires 5,12 to see if these are R+/- wires so that I can plug another input to it. But after splicing them up, the cd changer mode didnt kick off when clicked on CD button on the head unit.

In case it helps: My CD changer is Pioneer cdx-m9186zt (86270-48030) with a manufacturing date of Jan 1999.

I checked the radio wiring diagram for 1999 rx300 and it has lot more wire connections going into cd changer unit. Kind of confused what these 5 wires are for and how I can tap these to get my aux-in configured.

I think I numbered the pins the other way. Now when I match the pins, the colors and location are matching with the wiring diagram. It seems that the audio is not coming out of this connection. Its coming from the second socket which is a much thicker gray wire going into a blue socket.

vivawafs

It seems that these 5 pins are not at all for audio.

Here is what I did. I removed the other blue pin having a thick grey wire out. Then I powered on and tried to play CD. No sound and as soon as I plugged in the blue connector, the sound started coming again.

So now the question is any idea what this thick wire is and how I can tap into it to play my aux-in through it?

I mean I know this is audio. May be I just need to splice it and see the wires in it. I just need to try to adopt this threads config to the one I have and see if I am able to successfully place the relay and switch here.

I will try and let you know. Incase anyone has tried it, it will be great to hear what was done to resolve this config

vivawafs

The cable is a digital cable for Digital output based on the research so far. But I have no clue of what kind of interface it is and internet search has not resulted into anything fruitful.

Does anyone faced this issue?

I know as this is an old system, either are links are dead or just for parts. Not much info is available.

Does anyone have idea on what i could search on the net?

ilanh

Why didin't you try to use the TAPE input, so you basicly "kill" the tape option (which is useless) and use it for the iPod.

vivawafs

Well, I still have some tapes and my plan is to add more capabilities to my system. I am using the tape option to play for time being.

Hello. I just got a 2000 RX yesterday and tried this mod today, but got stuck. I got this far:



Now I need to connect a switch, but I don't know how. I know I'm supposed to connect it to 13, but I don't know where on the switch to connect it to. I also don't know how to connect it to the cigarette lighter and the ground.

salimshah

which switch are you talking about?

For switched 12v (when you move the key to off, power is turned off), you need to tap off the two wires going to the cigarette lighter. <= This is pretty basic. Are you sure you are not above your head in this mod [Excuse me, it is pretty hard to know the expertise level over the net].
