thanks for your help. I re installed older version as per your suggestion. unit worked good. Then re installed new update as per your advice. Unit worked good then.

However i did notice that when i was adjusting the window size from narrow to wide (2d sonar & map) this worked ok but when i wanted to adjust the window size on (DI & map) there was no option offered on the screen. Was this option left out of the new upgrade ? Randy

1. Power the unit on
2. Restore to factory defaults
3. Insert SD card (while the unit is powered on)
4. Follow the prompts
5. Wait for download to complete
6. Remove SD Card
7. Restore factory defaults

There have been unexplained issues with inserting the SD card and then powering on the unit...

I would suggest revert back to your original version of software...
Re-download the new update onto the SD card from the HB website...(in case the first time got corrupted somehow)
Follow the update procedure again with the new software version...
