Yes, there have been about four upgrades for the 727 over the last three years. When you install the latest software you will get all of those upgrades in one single file. I’m assuming here that you are running the 3.240 version software than you should get:
New depth algorithm to improve performance at high speeds. Improved FishID algorithm. Adds Sonar Recording. US2 transducer support. CannonLink support. InterLink support. Wide line track style. Aux Temp readout. Navaids shown in Bird’s Eye View. Support for HCSD (High-Capacity SD) cards larger than 2GB. Rotate through the menu tabs and items. Reset the connection to an InterLink after reprogramming it. Improve deep water depth algorithm performance. Improves Continuous Navigation Mode functionality. The current track is saved even if power is lost. Improves InterLink stability. Disables Input Voltage Low warning. Improved GPS refresh rate (if you are using a GPS Receiver).
