I don't know a whole lot about this unit, I bought it at an aircraft auction  that moved to a different location  and this was in a box with other equipment I have for sale on eBay as well.
 
This unit I could not test  but the  white parts remove tag that was attached to it suggests that it works. Of All of the equipment that was in box, one had a, I believe a pink slip which said it was inoperable.
This unit I could not test because I was told be a repair facility and numerous emails from parts company's that sell aircraft items told me it needs to be attached to other equipment for it to work, which I don't have.

I can send more pictures if requested. the item is used of course so it will have some normal wear and rear on it as you would expect from being installed and removed from what aircraft it came out of  and being handled.
One of the items I have ,some of the equipment have  a yellow services part's  tag/paper tag which tells me  it works, this had a white  tag so it kind of tells me it works.

I can not offer any guarantees nor will there  be any returns on anything that I sell regardless of  what i list on eBay. , if it were new, I would not hesitate to offer this, because it used, I can not. , its nothing personal, its just business.

THERE WILL BE A SMALL MATERIAL AND HANDLING FEE ADDED TO THE FINAL PRICE, SO PLEASE DO NOT PAY UNTIL I INVOICE YOU. AS WITH ANYTHING I LIST,  I DO  NOT PACKAGE ANYTHING FOR SHIPMENT UNTIL THERE IS A BID, SO DO NOT PAY ATTENTION TO THE WEIGHT THAT IS POSTED,, ITS THERE BECAUSE EBAY WANTS A FIGURE. ALL I CAN DO IS GIVE AN ESTIMATE ON WHAT I THINK IT  THE DIMENSIONS WILL BE AND THE WEIGHT  TO PROPERLY PROTECT IT AND PACKAGE IT.
