R170 - in car entertainment wiring diagrams

[Gordo]

Hi All,

I am a newbie and have just bought, (yesterday), a 2003 SLK 200 - my dream car - its got an aftermarket stereo which is very dated.

I have searched the forum, (probably using the wrong search words), as I am going to change it - the speakers on it aren't working by the sounds of it - does anyone have a wiring diagram for the speakers and the stereo.

Would much appreciate it if you could post a link if you have.

Thanks

Gordo
