Hello all,

i recently got interested in the z2, however i found that z1's are much cheaper to get. I know about updated bluetooth, voice recognition and a bigger HD, but is there anything that makes the Z2 better? Is there a way to upgrade the NAV software on the Z1 w/o having to download all of that stuff and hook it up to your home pc? I have seen on here many people have had issues with this process. I know a great deal about computer hardware, but nothing about this system. Any info is greatly appreciated.

Thanks in advance

The only difference is the navi software. You can buy it for $250 from a Pioneer dealer (they have to install it for you)
