Factory controls

**cruiser01** · 09-21-2004, 01:26 AM

Would it be possible to control a Carputer with the factory radio through the
CD changer buttons? I saw an adapter on some site to add an audio line-in
using the changer port but nothing with the controls too.

I amost got an Ipod because there is an adapter which relays audio and
controls using the factory changer controls.

I'm holding off building my own Carputer until I can work out interfacing
and some other issues. Something like this would really help.

I'm new to the forum and I did look through the other posts but I didn't see
anything relating to this. Kindly point me to the correct thread if I'm wrong.

Thanks!!

Suggestion: Tell us what kind of car you have. Year, model, etc.

This is the same dialemma I am in. A few manufacturers make AUX adapters for radios but if you use this you will lose interface with the CD changer controls.

God of cpu has a thread on how to make your own changer control access the PC through the gameport, though I am not clued up on circuits so dont understand it.

As far as I know, God of cpu's circuits and software are for interfacing steering wheel controls, not CD changer controls. Steering wheel controls are mostly very simple and analog. CD changer controls are more complicated and mostly digital (I think)...

Depends on what car do you have. BMW community completelly discovered I-BUS with all schematics of it to connect to serial.
VW has all the schematics available. I would suggest emulating either Alpine or Panasonic CDC and buy an adapter for it( see what's cheaper ). You can get the whole thing working for about $40-50.

I have a 2001 PT Cruiser Ltd if it makes any difference.
I'm going for a seamless low budget install. Using the changer controls from
the factory radio would be much prefered over installing a new radio, amp,
touchscreen, or whatever else it would take to play some tunes.

Adapter to Alpine-MBus for your car costs $80. You still need to get M-Bus emulator.
For instance http://joerg.hohensohn.bei.t-online.de/mbus/index.htm.
I'm working on Panasonic adapter atm and will have first Alpine board in 2 months.
