Anybody ever install the Terk XMDirect product in a 2006 RX330 w/ NAV and standard radio (no Mark Levinson).

I believe Lexus uses a Pioneer Head Unit; does anyone know the model number?

The Terk XMDirect (tuner & adapter) seems like a very cost effective XM radio solution. With rebate the cost is about $70 plus the XM subscription. It's hidden and I'm told integrates nicely w/ the radio LCD panel. It doesn't interact w/ the NAV screen like some more expensive products but if it works reliably and offers good audio quality it might be the way I go on my wife's RX330.

Any comments, help or suggestions would be appreciated.

Thanks!
