PhatBox

Looks like they only have them for Non Nav 99-03 Prius.

 

Seems a mite pricey at $699 for 40GB. Even if it worked for other years and options, Amazon.com has a 60GB video iPod for $369. IMHO, if you got that and spend either $159 for a DICE (2004-2005) or $299 for a VAIS (2006) iPod input you'd still come off ahead (and with an easier installation). It also looks like you have to pay $14.99 for the software.

The voice part is interesting, though.

 

I have one in my Audi A8 and I *love* it. The really cool thing about the PhatBox is that it integrates with the factory stereo through the changer controls. The PB software generates voice prompts for all of your albums, artists, and songs so you can select them by name. I was VERY disappointed that they don't plan to do a PB interface for my '06 Prius /w Nav.

Yes, it's pricey, but you can often find them discounted in one way or another. Some Audi dealers were selling them for about 1/2 price for awhile. Also there have been some deals on Eeekbay.
