Sorry Greg - But I did use the Humminbird software to format the card - Humminbird PC to be exact - it has an option to format the SD card. And I just checked, it is a standard 4G SD card, not an MMC. Also I think I am using firmware version 4.180 (with the PNG screen grab format) - and my Humminbird account is saying that is the lastest one - Could you check that is correct, and do you still think it is a card problem ? Also, if you still advise getting a Sandisk extreme III, will it support the 4G SD and does it make any difference if it is a Sandisk extreme III SD HC ?Humminbird_Greg wrote:The Humminbird software cannot format memory cards. You must have been using what was on your computer to do so. That 4GB card is an SDHC cards isn’t it? To properly format it you will have to use some different software to format it properly. I have never used it but someone had posted this link:

Try fully formatting your memory card and test it again.
The last software update for the 987 is the 3.940 version. Make sure this is what you are running.
We also recommend running the SanDisk brand of SD or SDHC memory cards. If you are going to be doing a lot of Sonar Recordings, I would look into getting one of their faster SDHC memory cards like one of the Extreme III’s.
