Just purchased my 2012 Prius 3 and I was wondering how I can download the 2.1 update. Since I just purchased the car, I don't know how long I am going to have to wait for a USB stick to come in the mail...
We re'cd a USB stick in mail today with upgrade on it. This is about 3 months after buying. It will come on it's own I think in time to your address. If the info on thumbdrive is not per VIN then you could probly use any one's to upgrade of the same type vehicle. I've not looked at at the contents of the drive just guessing. I'd gladly mail you mine as I don't see any advantage of keeping it around after I upgraded. The upgrade BTW is quick and ez. ps - thumbdrive has 302mb on it in 2 files and is 2gb drive Rec'd from : Toyota Program Headquarters 2175 Crooks Rd Ste 101 Rochester Hills, MI 48309
