My E27 came with KVH quadro, and after much suffering I got them to work for a while. But they were flaky at best, and spares can only be got from Ebay at highly inflated prices. I was able to sell my entire (partially functional) system on ebay for almost $1000.

My recommendation: rip it out and sell it on ebay (people need the parts). Buy a TackTick system. They are incredibly reliable and you can get rid of your ship's battery for racing...
