The unit is in great condition, i followed the Hummnbird instructions to the letter, including reset the unit to factory default, unconnecting all peripherals, tried with several different SD cards, 4,8, and 64...
Customer: replied 1 year ago.
to repeat, the unit reads the 2 different NAvionic lake maps I have therefore the unit can read SD cards
Customer: replied 1 year ago.
The error message when I try to export the waypoint is simply that the export failed.. the SD card is unlocked and I tried on the 2 different slots available

Again. Hummingbird instructions were followed to the letter. I have no additional info

One thing I would suggest checking if you haven't already is that the write protect tab is in the proper position. Make sure the small piece of plastic that slides on the card is slid up.

If this doesn't help, then the problem may be that the SD card slot needs to be cleaned. In fact, this is more likely the problem since you are unable to save to and successfully read the update from, the SD card. This is simple to do - you just need an SD card cleaner that will slide in and clean the contacts. Here's a link to one.

The tab was up on all as cards. Also I stated earlier that the unit read navionic map sd cards on the 2 slots so they are not dirty
Expert:  Michael Hannigan replied 1 year ago.

The next thing I would do is a reset so you can get the update installed. The catch 22 is that you aren't able to export waypoints. If you select one or two waypoints do you get the same result?

Customer: replied 1 year ago.
You obviously didn't read my comments. I did the reset. And the unit does not allow to export only a few waypoints

Based on your answers you don't know how to fix this. No lease cancel immediately my membership. I need written confirmation that I will not be charged monthly
Customer: replied 1 year ago.
Please review and update me on the membership situation.
