Clio 200 and 4th Gen' iPod

Hi,

Got my new RS 200 in December, and have been using the wifes nano with no problem to date, then finally got round to replacing the battery in my 4th gen' ipod yesterday. It has 18gb of music loaded onto it. But the stereo, the upgraded version, does not recognize the iPod when I plug it in. Does anyone know why? Any solutions to the issue? I have searched but only found posts which are irelevant to my issue....

what am i doing wrong.

The iPod is connected via standard USB from it to the connector underneath the radio/behind gear stick.

Help much appreciated.

Cheers,

Richard
