Thread: head deck controlling winamp

how u might ask?

if the pins on the back controll a stacker then each button that is used by the stacker must be one of the PINS.. so left right 1, 2, 3ect would all have a pin and when pressed that pin would turn to a high state. and there would be one common ground.. and then 4 wires for the audio,
i know the 4 audio ones.. i just havent riped the deck out yet to find each button yet..
now.. there are heaps of winamp plug ins that let u controll winamp with a joystick..

using the pin outs on the deck and each pin that corisponds to a button hooked up to a relay which will connect the buttons on the joystick.. so the relay switch will take place of the buttons on the joystick.

using a 4 button joystick u can have 8 controlls.

what i dont know is....
how much load each pin on the deck can handel? relays arnt much but will they be too much.. and how many volts they output.. im guessing 5-6v? to control some IC's?

and my main concern is. with the relays constantly clicking and clicking.. they might cause some interferance on the screen or in the music?
Can u get solid state relays? or can someone tell me how to make this solid state somehow???

and last question (i promis) does anyone know the Vout of the joystick (com) port?

Thanks
mick

i dont think cd changers work this simply, as i understood it they dont simply use high and low to speak to the head unit but rather the system operates more like a serial port sending different "codes", but correct me if i'm wrong

The fact that there are companies out there that make a business of making adapters to turn a cd connector into rca inputs at 100 a pop seems to lead creedence, as most decks that are cd changer caapable wont swich into that mode unless it detects a changer connected (which is what those adapters do).

the pioneer decks dont have to detect it.. in the options when the deck is off u have to select AUX on or off.. and then it will come up.. and there are 4 wires that are for the audio input. ive used em b4 and a friend uses them on the a pioner deck to play his dvd player..

how can companies sell em for 100? cus people buy em

as for the signal from the buttons.. i dont know if its encoded likeu say or not.. i was guessing and hoping it wasnt.

here is a pic of the pin outs..

all car stereos use a 2 or 3 wire serial buss to send data packets from the stereo to the cd changer here's the deal it's two way so you need the data to go in both directions and keep doing so or the stereo will switch to the radio tunner here's some ideas I had when I wanted to build my own phat box aka the kenwood music keg now on a pioneer you can get a aux adptor that gives you aux in and a cd changer at the same time if you cut the cable you just get aux if your model has this feture this adptor will keep the stereo on aux and not switch to radio. In theroy now you need to find the data wires and hook up a data loger to them and log the codes from the buttons you need on the stereo then you need to find a plugin for girder or write a software interface program to tx and rx the data from the stereo and pc and winamp now this is all just some thoughts I had about 2 years ago I don't even know if the stereo will send data or receive it when it is in aux mode if you can get the protocal list from pioneer or log the data between the stereo and cd changer you can wire a serial port to the stereo and write an interface program logging is what you will need to do because pioneer won't give you the protocal list and figureing out what is command data and what is track text data will be hard to say the least and then you need to know how to program so unless you have lots of time money and programing skills sell the pioneer and get a kenwood stereo and music keg witch is just a 75 mhz pc runing embeded Linux it's cheeper and more reliable than a home made project I have a pc in my car now and I kinda miss my old music keg somtimes because it was so easy to use then again the pc does so much more gps games tv xm radio music videos dvd's ect. and then there is the cool factor

You can control Winamp with an OEM VW/Audi stereo headunit through VWCDPIC: http://www.k9spud.com/vwcdpic/ AFAIK these are the only headunits that can do this so far - hopefully that will change soon.

Very possible to do what you are thinking, but very complicated.

can someone post the pin-out for the the 9-pin GM input connector pretty please

port20:
the pioneer i have doesnt need constant feed back to stay in the AUX mode.. i can select it to show up in the options and even if i dont have anything ocnnnected into the bus cable spot it will stay on and wont turn back to radio...

as i said earlier. a freinds using the 4 pins in the pic i posted to play his dvd and he didnt have to put a constant line feed to keep it on AUX mode..
the bus cable might have some constant feed line if u are using a stacker so AUX is automaticly shown when a stacker is conected,, but it isnt needed for it to stay on..

im guessing there will be some 12+ trigger from the head deck that will switch the stacker on.

This is a very cool idea.

I have a Kenwood deck and wanted to be able to control my Delco factory changer with it. Doe anyone know if this is possible? Or what the kenwood pin outs would be.

It would be very nice to control my DVD player and WinAmp also.
