without NAV?

 

You can get the Sony sound system without navigation. You cannot get cooled seats, only heated.

 

From what i have heard there are 3 different systems.

The Low end that has no subwoofer and lower power output.

The medium system that has the subwoofer and 700w

The High end with the 700w and subwoofer and nav screen control.

This might not be 100% but this is info i have found in the last couple of months

 

but what would be the difference in 700w sub system and the one with Nav?

they are both the sony system no? i just thought one had nav and one didnt.

 

The nav has the hardrive based system where ya can store music on the system, It will also let you rip cd's to the hard drive and has all the album art stored on the hard drive. As well as the hundreds of other functions the nav lets you have control off.

 

ok, i see what you mean now. but the 700 watts sound is still the 700 watta sound....no difference in output, right? or sound quality

 

Output will more than likely be exacty the same as its prob using the same amps. But the head unti is another matter. I did read somewhere that the nav head unit wernt made by sony but i am still finding it hard to find info about the systems specs on each version.
