Howdy all: I got my Prius with option package 4 so it didn't include a cassette player. I have a long commute so I listen to books on tape (unfortunately, there just isn't nearly as many books available at this point on CD). I called a couple of dealerships and one told me that it would cost $1,100.00 to have the 6/CD changer compo Cassette system that comes with the higher option packages installed and the other one told me that the 6/CD Changer Cassette player combo isn't even available anymore. I know there is a slot under the current stereo system where I might put in a after market cassette player, but I am very leery of having anyone but a certified mechanic install something that is obviously going to involve getting inside the front console and messing with the wiring. Does anyone have any ideas on how I might go about getting a cassette player installed without having to pay $1,100.00? Any ideas would be greatly appreciated.
