Hey All
I'm writing a detailed how-to with photos and part numbers but work is busy so it is taking a while.
Here are some simplified instructions and the wiring diagram (most important thing)
This mod uses the CD stackers (i)left and right audio channels and there grounds (ii) 12V supply
The 12V signal (and switch) is needed to "tell" the stereo to switch to AUX mode because there is no button
1. Remove plastic centre dash surround
2. Remove plastic gear stick surround
3. Drill a hole for the switch and a hole for the audio jack
4. Araldite audio jack to back of gear stick surround (mounts neat and flush with plastic)
5. Push switch through front
5. Solder up 12V power off take (Y-junction in wiring diagram)
6. Solder up audio jack and switch as per wiring diagram
7. Solder up 8 pin DIN plug as per wiring diagram
8. Refit gear stick surround and feed cable along right hand side then up right hand side behind when the centre consol surround was
9. Pull radio out and plug DIN plug in. Refit Radio
10. Solder 12V off take to +'ve cig plug terminal as per wiring diagram
11. Refit centre consol
12. plug in mp3 player, turn on switch (stereo sould say "LINE") and listen to your tunes!!!
Took about a day and cost me about $15.
Works perfectly. You do need to have the stereo volume 2 or 3 notches higher than you would have if listening to the radio.
Enjoy
