[CA] Trouble Uploading Software Update to a98

[GoodChance]

I have an a98 currently running software v.14.36.

I purchased a new SanDisc (mSD) with 8GB of storage.

Went to the Raymarine website and downloaded v19.03 to the root file of the mSD card. The mSD card was formatted to FAT32.

When follow the Raymarine instructions for uploading this newest software from the mSD card, I get a "no data available" message from the a98. Tried three times. Same message all three times. In between each attempt, I deleted the original v19.03 software from the mSD card and loaded a new.

FYI - Last week I was able to use this same mSD card to transfer waypoints into this same a98 unit.

FYI - the a98 is connected to an a68. The a98 is the Master.

I would (could) attempt to use my iPhone SE as a hotspot but as I understand, only Raymarine software after v.15.59 can be updated using wifi.

Your thoughts how to proceed?

In case you are wondering, the a98 is otherwise running fine. But for some reason, the a98 is not recognizing the newly installed RD424HD radar. I'm thinking that this could be a software issue.
