I own one in unknown (but probably not working) condition. After talking to the folks at Track It, you would likely be best served to buy a new one. They said 10 years is about the max lifespan - and ours is one of the first ones. It came with the boat, and we don't currently use satellite. They offered us $100 off with trade.
