There is a 2001 ver 1.0 is this the same one your speaking of? If not I would wait on updating, as I have heard that 2002 would not be out until the end of this year.
As for the cost? They are saying anywhere between $400-$1k.
My source on this info is other nav web rings. So as for the validity....??? who knows. I do know it tells you in your NAV instructions that came with the Prius, to contact your Toyota dealer as it carries its own part number. THIS WILL BE THE ONLY WAY YOU CAN BUY AN UPDATE. (Im sure until some with those new DVD burners start bootlegging them, especially if they are very expensive to update) Or they get stolen during a test drive of a newer model Prius. :!: Im not condoning this :!:
The DVD disk can be changed out by yourself. The company that makes the disk is a mapping corp. I believe there is another company involved that actually puts that mapping together in the form of the program for the NAV systems to use. These are also the same programs that are in Lexus.
Hopefully the price wont be that much. Im hoping less then $100.00 for us Prius owners. We shall see. Im also seeing a lot of roads not shown on my 2001 system. The numerical address is also backwards. Like my block shows the numbers going from north to south as larger address numbers to smaller, when in fact its the complete opposite. When I show my house on the block where I actually live the address is 895 instead of 814. 814 shows next to the nearest county road. Again the complete opposite. I wanted to see if they could correct this. But there is nowhere to write or call.
Ill shut up now. Just wanted to let you know my research I have done and my experiences. Good luck in PHX. Stay cool. I fly there at least twice a year, and you can have the heat.... :twisted:
Its located under the passenger front seat. But look at it from the backseat side.
There is some black twist locks that hold a metal plate on the front of the DVD. After that its like anything in your home. Has an eject button. The key if Im not mistaken has to be turned on in order to get power to the player.
I would turn the key off after you take out the disk. Then turn it back on when you get ready to put the disk back in. The front console display will tell you that there is no system disk.
