Mazda 6 Stereo interface
This isn't repeater related, it isn't even Ham related. I spent the last 7 or 8 months working on an ipod interface to my Mazda 6 stereo.
It emulates a Mazda tape deck and allows the factory stereo controls to manipulate some of the ipod remote functions. It also
provides a direct ipod audio link to the stereo. I wrote a blog-like account of the reverse-engineering
and design process.
I'll post design data when it is ready for prime time...
