Radio Mod ( aux inputs )

melloyellow · Post by **melloyellow** » Thu Nov 27, 2003 11:21 pm

Does anyone know if the radio on the 2003 S-10 has external inputs on the back? I am looking for a way to directly connect my iPod to the radio amplifier. I currently use a tape cartridge that does it but way to much hum.

Thanks
Bennie

I didn't see any on mine when I removed me factory unit. It has RDS.

Nope...no external inputs. The best thing you can do with the stock head unit is replace it.

I could have sworn there was a thread discussing this, but I couldn't find it.

I use the Irock FM transmitter for my input.

What about NEO from this thread : Found a use for the AUX feature on the OEM Radio
I'm not an "audio-phile" so this may be a totally different application

I think I am going to order this unit next week for my truck. I don't think it will help with what you are wanting to do tho...

OK, I removed my cassette player, now why can't I use the connection to play my DVD player through it's inputs?

Here is what is available - Battery positive voltage, Entertainment and comfort serial data, ground, remote playback device audio common signal, remote playback device left audio signal, remote playback device right audio signal, instrument panel lamp fuse signal voltage , radio on signal.

Why can't I wire a head phone jack to the audio signal wires and play it through the stock stereo?

I could wire up a switch for the radio on signal too.

i always look at things this way,if logic says it can be done ill do it, if i do and something isnt working there is a logical reason for it not to work,and then there has to be a way to make it work, or it will never ever work, the laws of physics are against it.sooooooooo what do i mean by all this nonsense, if you think it "should" work, give a whirl.

and tell us how it went.

Post by **HenryJ** » Mon Apr 26, 2004 7:05 pm

Great, as usual I am on my own here

It can be done.

The audio inputs do indeed play the DVD player (I used a portable CD player for testing purposes) Now I just need to figure out how to simulate the cassette player having a tape in the deck to turn the input on.

So far four wires must be attached to the cassette player-
Battery positive voltage, Entertainment and comfort serial data, ground, radio on signal.

voltage and ground are easy they power the deck. serial data has 12 volts. radio on signal has 12 volts.

Disconnecting radio on signal while playing ejects the cassette and stops audio.

Disconnecting the serial data while playing disables the eject button, but audio continues.

Anyone have any ideas on how to make a switch to turn on the inputs?

I ran out of time tonight, but I'll give it a shot again soon , maybe.

Check the link on my post:

they had the aux in kit. They do list blazer 98-02 so maybe it will work on your truck. there are a few other makers(PIE and another that starts with a P) that make similar converters.

Cheers,

Isn't it something that I can wire up myself, without spending $80 or more on a box?

Sure seems like $10 worth of parts at radio shack and I should be able to do anything

See if they have converters there too for your radio.

ok as you can tell by my wiring I am not to shabby electrical things.. ok let me get this right you want to wire your (lets say cd player for now) cd player to play cds and you be able to hear it on your stock system ..correct? ok if I am wrong on what your intent is correct me.. but here I go.. one way which is the easiest is with the tape deck.. you can use the car kit I am using for my dvd player which in my opinion sounds great except for a slight hummmmmmm...

ok another way which is cheesy .. is to hook up an small amlipfier and run that to all four door speakers.. now you have rca inputs on the amp .. so you plug in your cd player to your amp using a headphone jack to rca converter.. or you can make one.. I might even have one lying around but im not sure.. ok so you set up your reomte wire to the amp on a switch if you want.. the amplifier is only used as a convertor and to amplify the sound from your cdplayer.. I do have an extra amp lying around.. .. so now all you do is hit the switch and push play on the cdplayer to hear sound.. I had a set up like this on my way back to vegas for my dvd player.. I suggest the cassette deck thing...

ok since you had the remote located casette deck you might be able to use those inputs ...if I read correctly.. you have a right and left channel. coming from your old tap deck to you radio.. I looked at the wiring schematic and it seems like if you put a headphone jcak it might work.. question though how many wires are in each channel.. in the rhchannel you should have a + and - for one side and then another+ and - for the other side.. try copying the link below into your browser..

The inputs are no problem and work, it is the activation of them that poses a problem.

Right now I can intercept the inputs from the cassette , attach my acecssory and play it through the stock head unit, but only when there is a tape in the deck and playing.

I need the correct voltage , lack thereof or signal for the remaining wires so that I can eliminate the cassette deck and use a simple switch to turn it on instead.

Busy with enjoying the summer, and have had other "fires to put out".

I'd still like to delve further into this , but just haven't made the time.

I was bored this AM so I did some looking. It appear that nothing is available for my 04 at this time. GM changed somethinbg and the PAC site states that the 04 s-10 etc... are excluded from their lists. Hopefully soon.

Thanx!

However, I wimped out and bought a Belkin TunCast II last night. I wired it into the cigarette lights and it fits neatly in the ashtray. It was 39.99 so it will work OK for now....

This looks pretty good. It is the first one that I have seen listing the vehicles application, not just "GM pin count". It does refer to the cassette input and states that it plugs into the rear of the head unit.

I LIKE CLEAR INFORMATION! and lots of it!

This is the one for my 2001- GM9 AUX ADAPTER

This one gets my vote. It is spendy , but I'm going to reward the efforts with my $ and order one.

UPDATE: Order processed and received a tracking number. This outfit works pretty fast so far! I'll let you all know how things go

So far "two thumbs up" for Autotoys.com

I have yet to hear anything bad about them.
Let me know if the harness works. I may go this route but it will have to be a little later. I've got some mods I have to buy for my Grand Prix first

Well, I can't say that I am pleased with them requiring a signature for delivery

It took three trys to connect with UPS. I wish they (Autotoys) had not done that to me.

The unit works great the install took close to an hour, since you have to tear the dash apart and remove the head unit to gain access to the cable and connector.
I suppose you could plug it right into the cable that connected to the remote cassette player. Both male and female connectors are available for this reason.

I plugged right into the back of the head unit and barely had enough cable to extend down for mounting on the side of the center console. Another 6" of cable would have been nice.

It is really nice to just push the aux button and what ever is plugged into the RCA jacks plays through the stock stereo

also no more batteries for the Irock and trying to find a clear station while traveling

Just the way I have been wanting it!

My thanks to all those who directed me to the right part

Excellent! I may go this route soon. I wired my RF Modulator into the cigarette lighter and so far so good in the local area. However like you mention, somtimes the RF is interfered with in from local stations.

If, I read all of this correctly my stock 2002 rds/am/fm/6 CD changer head unit does not have an AUX audio input in the back of it? I purchased an XM radio with modulator (requiring a jack to plug into the existing FM radio to work).

There goes another perfectly good duck
