Spanish Wells, Boat bound

We were all going to head to the Shipyard restaurant for lunch, but it is rather rough and we would be quite wet by the time we get there. We all decide to hang on our boats for the day. We work on various projects. I was having some issues with our AIS transponder and the vendors technician recommends that I download and update the software. I do as he says and the units stops working all together, so much for the upgrade. I now have a $600 brick. No AIS transmission or reception.
