Garmin GPSMAP 498 upgrade card

I'm looking for 1) suggestions (than purchase a new unit) 2) one of the data cards that Garmin used to do their updates on the GPSMAP 498, or 3) more information on "Preparing SW Update Card" that is mentioned in the manual. Further background is below.

The unit is about several versions behind the last version that Garmin issued. The last version fixes several problems that I'm having. The unit works fine except when these known problems occur. The biggest is that it doesn't track speed or direction (depth still works). I've tried restarting it, letting it sit through the satellite finding process, immediately clicking ok, having it Initialize Position (usually only needed if you move the boat more than a couple hundred miles from the last position, which I sometimes do - the 26D is a trailer sailor after all).

When I contacted Garmin support they indicated they no longer support that model and don't have any of the cards around that they used to send out with the upgrade on it. Their old process was to take a security deposit (I think it was about $50) and send you the card. You did the upgrade and then when you returned the card the deposit was refunded.

I'm hopeful with all of the technies out there that someone decided it was worth keeping the card or made a copy of it that I could borrow or knows how to do the upgrade some other way.

Thought I give this a bump since most of the folks are not sailing. Anyone have a 498 that could help out?

I have a Garmin card for my GPSMAP 492 with the latest SW version 3.40. My chartplotter is the same as yours except you also have the sounder. According to Garmin, SW v3.40 is the current version for both the 492 and the 498. PM me if you want to make an arrangement.

I know this thread is several years old but I also have a Garmin 492 with old software. Any chance someone has an update card and reader?

I have both the reader and the version 3.40 upgrade card. All you need is the upgrade card to install the latest firmware. I will be happy to provide. I can send you the upgrade card with your sworn promise to return it, or if you have a card you can send it to me and I will load the update onto it and return it to you.
Advise your wishes.
