Renault Laguna 1997 Philips Cassete/radio aux input?

I ve recently bought a Renault Laguna MK1 (1997) 1.8 RT and I am trying to find out if theres possible to get an aux input. It has a free 8pin connector(iso) but i dont know if I can get an adaptor to get a aux input to connect my phone and ipod. So is there a way(other than the cassete adaptor because of poor quality )or do i have to chage the unit?
