Swift

Just purchased a 2008 RX 400h w/navigation system. Is it possible to get seamless integration of both satellite radio (Sirius, not XM) and an iPod. By seamless integration I mean that I can use the navigation screen, built-in controls for both units. It looks like with the OEM equipment I can get one or the other. With Vaistech it looks like I can get integrated satellite or integrated iPod and an AUX jack for the other. Any suggestions/recommendations? Thanks.
