ive only ever dealt with my classic minis aftermarket head unit and that was pretty simple , i thought that my punto would be much easier as iso connectors are as standard , i bought the adapter for my sony head unit to fit the grande punto as well as the faceplate. i thought that all would be good and it would work as soon as id plugged it in. To my supprise nothing happened , i ensured everything is plugged in as it should be and still nothing. any ideas why it will not power the head unit and how to go about the issue as im going to be fitting a vibe cbr sub in pretty soon and wanted a head unit with a sub out level output?

cheers
