a coulple of newbie PMM questions

[jcharles00]

if this stuff is covered in a FAQ, please point me there.. i've read the wiki, and been all through the phatnoise knowledgebase, and some of this stuff is just confusing..

i've got PMM 1.87 that came with my phat box.. i see they are on like 3.7 or something now.. it also appears that you have to pay for upgrades. can anyone fill me in on this stuff? do i need/want the upgrades?

i've read here a little about the SSA and VOIT navigation. my phatbox was an audi model that i'm going to use with a kenwood.. do i need to worry about this stuff? i really don't care if it speaks track/album titles as long as i can see the names on my HU display.

You can see the names, and the upgrade is free you just dont get the 'new features'
