Spent the weekend playing with my new (to me) '05 RX330 with Navi, ML, and RSES. Love it all!

Question about the ML system - the sound appears to be coming from in front (windshield area) no matter how I adjusted the "POS" settings (had the settings to Driver, Front, and Rear). Is this how the system is supposed to work?

I tried adjusting the Fader to all rear, and only heard sound coming out of the cargo area - I would have expected sound coming from the rear seat door speakers as well.

Thanks!
