Iphone connection

Has anyone fitted a Dension Ipod/Iphone dock to their Boxster?
Mine has been fitted but not by me!
It won't recognise my Iphone 3GS 16GB Model,it obviously worked on the previous owner but not sure what device he used probably just an Ipod,but not sure!
It just says device not recognised or not activated.
Do i need to do something on the phone ?
Any tips would be great

Software update?

Try a new cord.
