I had understood that was because there were not enough responses from owners of either model to be included in the survey?

Rillo - huge thanks. I tried a newer iPod version as you recommended and the problem is solved. Major irritant removed. I am now adapting to the slightly harsh suspension, albeit less so to a trim rattle somewhere around the rear seats. At least my iPod now drowns it out! Hopefully the dealer can resolve when the car is next in. In any event, passengers praise cabin comfort levels to the skies, so perhaps I am over-sensitive to some of these things.

I have issues with my iPod connection on my new RX 450h also - it is sometimes ok, but I frequently get a "connection fault" message, with no sound or other functionality. I also have an iPhone 3GS which plays music directly onto the Levinson audio system via Bluetooth - perhaps it is crowding out or confusing the software in some way? Otherwise, I have had my RX 450h SE-L for 3 weeks and overall am impressed. The cabin is a pleasant and really spacious place to be, not least given the RX's relatively compact exterior dimensions. My only moan so far is the surprisinly harsh ride around town - no doubt made worse by the 19 inch wheels. When will premium maufacturers abandon their POINTLESS attempts at *sportiness*...and specify sensible wheel/suspension settings fit for the UK's pothole covered roads? Only Mercedes seem to "get it".
