fixed the master/charts issue as u said. Not much changed with what i was able to see on my charts. It looked just about the same to me.....but in the catalog, i was able to unlock the bahamas fishing charts i purchased.
As for the sounder, it was not on the sensor list.....for some reason the TZT2 was listed as the sounder, so i switched it back to Dff1 and both trasnducers worked again.
As for the charts in the bahamas, Furuno said the eastern bahamas are not a preloaded chart, so they would need to be purchased....even the raster/noaa charts for the eastern bahamas. CUba was also not visible. The bahamas charts i purchased were fishing charts, and not very detailed. They recommended a different chart to purchase to get coverage of the eastern bahamas, but im not going to buy charts to use for a month or 2. The western bahamas and bimini are part of the preloaded charts. I thought all NOAA charts were free.
For some reason the Yamaha Commandlink digital gauges also had some issues all of a sudden and were not communicating with the GPS so i was not getting any speed on the COmmandlink, but i was showing speed on the TZT2. I was told it is probably an underlying NMEA backbone issue, not a Furuno issue.
