Back story:
It came with my truck. I don't want it. 'Nuff said.

I never tested it. I've no way of knowing if it works or not. Buyer Beware. I've no intention of shipping (except to the garbage). Your welcome to test it. I'll drive a reasonable distance to drop it off. Say to Hulen Mall from Glen Rose.

Here's the specs I got off of eBay.
