Thread: GM (DELCO/DELPHI) Aux Input

Superdave

I just read your post while searching for info on the PIE adapters. I'm looking into using one.

it requires a cd changer to be installed

Actually, the installation instructions for the adapter say that if you have a CD changer it has to be disconnected . In fact the PIE adapter emulates the changer so you cannot use the changer.

See http://www.pie.net/gm9_aux_inst.htm
also http://www.pie.net/aux_appl_gm.htm#chevrolet
and http://www.pie.net/sec12sb1m.htm

What you do need is a head unit with changer controls, which according to the above pages, the 2001 Silverado does have. I have a 2001 Suburban and I assume the CD/Radio is the same.

I found the AAI-GM9 adaptor after getting a 99 silverado for Christmas. It is a great little adaptor. After hooking it up I now have no need to ground by box and have zero noise (engine whine or invertre hum). I paid around $50 for it and had a thread in Jan about it. Search for AAI-GM9. Insatll pics are at www.thethorns.net/install.html . You do have to have a working AUX attached for it to work. I have a cassette in the stereo and a Aux CD. I boot up the computer and when I get the display on I push the CD button on the stereo and then have to switch the Aux selector switch connected to the adaptor. You can have the factory Aux plus 2 others. I have an 1/8 in cable handy incase I want to hook up a protable MP3 player/Ipaq/etc... Let me know if you want to know the sites I found that sells it.

Heres where I ended up getting mine. They were a little slow getting it out (it was around the holidays) but for $50.32 and 4 bucks for shipping I was happy when other sites had it for $75. Main thing is tha you have a working AUX unit, you can't use it if you just have the AUX plug on the back of the stereo. I have to have a CD in the player for it to work. In the documentation it also tells you how to set up the switch with a 12V input that auto switches it to one of AUX but I didn't do it that way.

You really don't need it but all I had to do to have 2 aux inputs plus the factory CD player is plug in a couple plugs. To have the same thing the other way would have involved about half the cost of the device in RCA plugs/a good switch/time to cut,solder,tape the connections and then there would be no built in noise filter?? I guess I just thought it was worth it for my build.
If I ever sell the truck removal will be a piece of cake I guess it all depends on what your time is worth.

Thanks for the code guys it is correct. I was able to splice right in.

However, there is a problem with this method.......

The AUX input only works if the CD unit has a cd in it. I tried putting in a blank CD and it wont work. So what I have is the XM radio and the Cd playing simultaneously.

In other words the aux input button only works when the cd is playing, is there a work around this?

Thanks Guys.

has anyone had the same problem?
