iPod connection for a 05 Laguna

Hi,
does anyone know what the best method for hooking up an iPod to my car stereo is?
I had a Monster wireless one; but that was rubbish.
I could hardwire the iPod to my Mitsubishi Lancer's stereo..which was great.

My current car is a 05 Laguna; wireless might be the best and tidiest option.

Thanks
