Ordered this an found out I order two different things that do the same thing. So I don't need the Adbox1. Willing to sell for what I paid $100, shipped. I won't take less, it is new, opened but never wired it up. Has all the instructions and such. For some toyota models all you need is the wiring harness, AX-ADTY01 which you can buy at fry's or online for 20 bucks. I can't return it because I am past the number of days to get a return. Works with toyota/ lexus, 2003 and up. Works well with many other brands of cars too. If you have a second car non-toyota there is anywhere to search all the makes of vehicles it will fit. You'll just need the matching wire harness for your model vehicle.
