Connects2 don't do much stuff for the Becker head unit anymore.
I removed my head unit as the Becker Sat Nav is pants, with a Kenwood KDC74BT but it took a while to find a lead so I could carry on using the steering wheel controls.
The only company I could find was called In Car Tech. They were very helpful and supplied the correct leads which they make.
Works great. I can have iPod control via a front USB or rear USB lead or even connect via a 3.5mm aux. or BT audio stream. Great piece of kit which also has DAB.
