and use this pictures for more details. If you need help, ask me here. Atention: welding point is very small points. If you dont have experience for weld cables there, take help from someone which is professional.
Details for 3.5 mm Pinout
in audio 20, show to where is weld points zoom in
in audio 20, show to where is weld points zoom out
1- Soldering points is very small place. Need a professional person hand.
2- Left and Rights cable shown in pictures but also you should to solder Ground cable too on any corner of shiny abd bright steel plate (this plate seen up to word "MASSE" on last picture).
3- Before to solder cables, you should to pass this cable from any hole of audio 20. if not or if forget then your cable will stay between auido 20 device and his cover. Tehn cover of it dont close good. And in time because of friction this cover can cut cable. Therefore get pass the cable any hole from back side of device.
4- You need create one slience CD (search google how is) for you can listen music. Prepare a slience CD. If you can't do this, i will ty to help you about this too. Your connection will use actualy CD player output channel. For listen music, you play your mp3 player and push button "CD" on your audio 20. Then ths cilence CD will dont give voice to speake and only you will hear from you mp3 player voice. I hope understand this point.
5- Select a thick and resistable a aux cable for the solder. Becaseu thats soldering point is very small and you have few chance to solder. If you use thin ans weak cable, in time will destroy and/or broken. Then maybe next time you can't solder again thats points. Therefore to do one time with good and resistable aux cable and keep long time life. You couldn't be second chance.
Good luck..
(i hope you understand me becasue of i dont have good english language)
