I know if i get the navigation feature it will come with a screen but what about the 7 speaker 320 watt option its around $600~ i think i am still confused if it comes with a screen or not.

 

Only the Hybrid/Nav radio comes with the LCD screen....at least on the 2007 and earlier models.

 

For the '07, if the hybrid came with the Nav system as part of the (Premium?) package, then you get 7 speakers. If the hybrid came with the Nav system as a stand alone option, then you get just 4 speakers.

 

In 2005 the 7 speaker system was packaged with the Nav system.

In 2006 the 7 speaker system was packaged with the "premium package" that had heated seats, etc. but not Nav. In 2006 you could get the Nav with standard 4 speakers.

In 2007, I don't know how it came.

The picture for the Audiophile option on the 2008 FEH shows an LCD screen in the middle of the radio area. I would assume the option would be the same in the MMH. You could always contact the dealer or Mercury to find out for sure.
