Headunit Recommendation

[kingspice]

Hi there,
I am looking for a new headunit for my Clio.

Would like some decent ipod connectivity and also cd mp3 functionality with usb/sd if possible as well.

The one head unit I've spotted after a quick look is:

Just wonder if anybody has any recommendations or reviews on some head units

Willing to spend upto 300

Thanks
