RX350 & speech command question
 

I'm sorry if this is already answered but I have search this and other forums, went to Lexus' website and even went in and talked to a salesperson. But the salesperson said he didn't know if the RX350 had the speech capabilities I'm asking for.
I have a 2011 Ford Taurus with the Sync. Just for those that don't know what Sync is..... You can push a button and tell it who to call and where (i.e. home or cell). Also you can tell it what to play. I have a USB attached hard drive and I can push the Sync button and tell it to play a specific artist, genre, playlist or song. Can this be done with either the second or third generation RX350's??? And if so do I need the navi?? Do I need the Mark Levison edition stereo??
I would think if Ford does it that Lexus would be miles ahead.
Just a side note. I owned a 2005 RX330 but after both my husband and I were laid off and the RX330 needing a some expensive repairs, I had to sell it. Now I'm regretting it as I'm missing my Lexus. Finances are much better so now considering getting another one. Looking at the 2010/2011 RX350 but need to know if it has these speech commands.
Thanks for your time.
