I just bought this here a couple months ago and have never gotten the chance to install the unit due to medical issues. My wife has since bought me a brand new unit for Christmas.
Here is the thread where I bought if from 2K6 Taco with the pics and info;
This unit as described in that thread has GPS, Bluetooth with mic, backup camera capability. All harnesses and instructions along with original box are included. Exactly as I bought it from him.
I paid $500 including shipping. I will sell it for $475 including shipping. I don't have a paypal account, so payment will need to be check or USPS money order (preferred method and I will ship same day as I receive it).
