I have the factory 6 disk changer radio for sale. It's model # 86120-04131 and serial # MX118745. It is brand new. The stock radio was replaced with an aftermarket Nav unit. I'm not sure what to ask for it but there is one on Ebay for $85.00 so I guess I will start there (obo).
If you have something cool to trade that is Tacoma related I might do a trade as well.
Buyer to pay shipping cost.
p.s. I can email pic's if need be.
