oTo be clear if asking questions about the TZ PC software, please contact Nobeltec. If asking about an Furuno MFD ask the forum or your local direct dealer/distributor. Any TZT2 that was sold from Furuno USA will include a chart card that is inserted directly into the back of the machine. We do include many preloaded maps. The NOAA vector, NOAA Raster, and Army Corp Eng (ACE) river charts with some US SAT photos are free. The C-map, C-Mor and others require a chart unlock to be purchased. Under the original discussion you seemed to indicate your chart versions were most likely old and not up to date. To update any map which is located on the chip in the back of the unit, I explained it must be removed from the machine to be updated. That is still true. If you are looking at unlocking an area you haven't purchased, while it is true you could purchase an unlock code and it will unlock the older data that was "embedded" on the card that was included, it still wouldn't be the most up to date version you just paid for. To have the newest information, it would need to be downloaded and then placed on that mapping chip. At this point, I think you would benefit from talking to our normal support via phone. Provide them with your system ID from your unit so they can check if any licences have ever been purchased previously. They can also explain how you can look at the chart catalog to see what version of maps are have versus what is available now. (Our support numbers are 410-479-4420 or 360-834-9300)
