I just sold my 06 Tacoma and have the Pioneer double DIN AVH P4000 DVD Ipod ready head unit for sale. I am including the already wired wiring kit so you can just plug it in to the factory harness. I also am including the double din trim kit so it looks factory installed. It is in excellent condition (still have the original box) and includes cables for iPod, flash drive for music, and RCA external accessory inputs for a game or other device. Selling for $230.
FYI I also have a pioneer sirius bus adapter CDSB10, the sirius car dock a Sirius sportster sp5 satellite radio receiver that will allow you to have Sirius radio in your Tacoma and control everything through the pioneer headunit for $100.
Thanks for looking.
