Drove a new 2010 Camry at the dealership I work at today. Same body style, but a host of improvements inside. XM trial comes on the base model, and there is an AUX input and USB integration standard. As the Camry is a "Green" car I would imagine they'd be hitting the Hertz fleet fairly soon.

EDIT: Turns out the USB integration and XM radio only come on the Touring Package model, which in Canada is about $2,200 more at retail than the base package. They might not be on Hertz lots but you never know.
