Get her a RF tunner (radio tuner). That is the easiest solution. However, sound quality is not that great with these. If you want to do her right, take her car into a car audio store and have them hardwire an auxilery audio input so she can hardwire connect her iPod to the car’s audio system. It may be easiest to replace the entire radio with an aftermarket head unit that already has the aux input.
You can try one of these.

With this kit you can control your iPod from your factory Prius radio, charge the newer iPodsiPhones and the sound quality is just like a CD.
