We had to wait for high tide to leave Navimca and chose a short jaunt to Laguna Grande to ensure everything was running smoothly. Our chartplotter had to be downloaded onto our most recent computer but didn't recognize the drivers we installed. We called the company providing our navigation system just before we left and were told they didn't provide drivers for a 64-bit computer, that we needed an older computer. Also, the chartplotting program had been discontinued so we immediately purchased the replacement program which didn't do the same job. The next representative we talked to said "who told you that". Frustrations have been running high. Solutions are there but don't come easily.
