Upon further investigation on the Denison site, it shows that a certain adapter kit IS compatible w/ the RX330, although I'm confused how it connects to the head unit, unless somehow it replaces the connection to the in-dash CD changer:

iceLink v1.1 for iPod and certain 2003+Toyota/Lexus/Scion Vehicles

Compatibility:

Lexus 2003-2004 LX470, 2004 RX330

Scion 2004 xA, 2004 xB, 2004 tC

Toyota 2003-2004 4-Runner, 2004 Camry (w/ Nav), 2003-2004 Celica 2004 Echo, 2003-2004 Highlander, 2003-2004 Landcruiser, 2003-2004 MR2, 2004 Prius, 2004 Sequoia, 2004 Sienna (w/o DVD), 2004 Solara, 2004 Tundra

Please note that this kit may not work with the 6cd in-dash radio on certain models.

Details:

This kit connects to the back of the radio. Installation requires removal of radio. Specific radio removal keys may be required. Radio may require security code after installation. 3ft cable requires iPod cradle placement near the dash. Professional installation recommended!

Kit does not include vehicle mount. For professional mounting, please select one of the proclip mounts from the related items list.

Also, they have a couple of mounting kits specifically for the RX330; here's a few photos of the center-mount model:

Regarding the Denison unit...

To connect it to the factory stereo, it seems you need a unit with a separate CD changer, rather than one that is integrated into the head unit.

It connects the iPod to the stereo through the existing CD changer cable that typically runs to the glovebox or trunk:

Retail boxed and end-user installable kits connects to the trunk end of CD changer cable for BMW,  Mini, Audi and VW vehicles.

So, I don't think this is a viable solution for the RX330.

Bought a RX330 about a year ago and now regreat forgoing the NAV option and not interested in after-market add-ons.

Is it possible to have it installed by a delear?

Also, could you do so without upgrading to the Lev sound system?

Thanks in advance for any feedback.
