Err, your wait for the cheeper device (about half the factory cost) ended quite a while back :P

Here's a few pic's of the aftermarket device installed on Lexus, Toyota, etc. And it works great, and it only takes 30 minutes for a numbskul like me to install.
Enjoy
For those o you out there with an '01 LS430 with the in-dash 6 disc changer, the Dice will NOT work...do not waste your money. There is mis-information on their site. Also 2 of their sales agents said it would work. I called back in and one of their techs confirmed that it would NOT work for my car. I thought I had found a deal...for those out there that are lucky enough for the Dice to work, you are lucky...still looking here.
