HDS 4.0 Software

[Billy V]

Has anyone has any problems performing the 4.0 software update on their HDS 5 ?
-------------------------------------------------------------

I am familiar with the update procedure Video posted on the Lowrance website, and have used it to update my unit once before - but the 4.0 will not upload to my HDS 5 Nautic Insight.

I downloaded the 4.0 software onto 2 separate SD Cards and tried both of them - no luck. Then I took both of the cards to Westmarine and tried doing the upload on 2 of their display units - still no luck.
-None of the units I tried would display the prompts and walk me through the upload as it has done in the past.

I'm wondering if Lowrance has a bad download posted on their website.

Any ideas what is happening ?
