The navi system is completely unrelated to iPod connectivity. All 06-08 models come standard with an AUX audio jack in the center console, which will allow you to connect an iPod to, but you cannot control the iPod with the audio system. You will still need to control the iPod manually.
There are aftermarket kits that give you iPod connectivity, including some control from the standard head unit, for all TSX models. Acura dealers offer such a kit as well.
The 09 TSX comes standard with an AUX jack as well as a USB port to connect an iPod to and allow control though the audio system.
