Firmware Update 1.300 (Latest)

  • For the best image from MEGA Live in most water conditions use the default settings:

    • Dynamic Contrast: Balanced
    • Sensitivity*: 10
    • Contrast**: 10

  • If you are in shallow water or if you’re experiencing clutter on your screen try:

    • Dynamic Contrast: High
    • Sensitivity*: 10
    • Contrast**: 10
       
  • If you are in deeper water and are looking for increased bait tracking performance try:
    • Dynamic Contrast: Low
    • Sensitivity*: 10
    • Contrast**: 10

*Sensitivity will decrease or increase the apparent signal strength of all of the returns on the screen. Always start at 10 and then increase or decrease as needed.

**Contrast will decrease or increase the separation in apparent signal strength between stronger and weaker returns. Lower contrast values will help when trying to track smaller baits or targets while Higher contrast values will help remove clutter from the screen.

Software Prerequisites

Personal computer with Internet access, a formatted 32GB or smaller SD memory card, and a USB Memory Card Reader. 

In addition to this MEGA Live software update, users must first install the latest version of control software for compatible HELIX, SOLIX or APEX models.   Failure to install the head unit software first can cause issues with the MEGA Live update not successfully processing or could cause sonar performance issues that will remain until all updates are performed successfully.  The TargetLock features cannot be used without successful completion of these updates.   

Instructions

  1. After installing the appropriate update to your compatible Humminbird unit, download the update file to an SD card.
  2. Go to the Accessory Test view and confirm that MEGA Live is connected and that the version is 1.130 or newer.
  3. Insert a SD card with the new MEGA Live software.
  4. Respond to the two prompts that appear to start the update process (Select Yes and then No).
  5. During the update process you may notice a few “lost source” notifications. This is ok. You do not need to respond to these prompts.
  6. Wait until the MEGA Live disconnects and then reconnects with the new software version displayed on the Accessory Test view. This process could take up to 8 minutes! Do not pull the card out, restart the HELIX, or restart the MEGA Live.
  7. Remove the SD card with the update once the update is complete.
