I asked garmin about doing that, this was their response. something tells me the person responding was not very knowledgeable.
I would like to upgrade my 2 93sv plus units without spending another 400.00 for 2 cards, is there any way to do this? specifically I just need oklahoma/texas lakes. this is what I got from navionics chat. Serena B Thank you for contacting Navionics. My name is Serena. Who am I chatting with today? Navionics is processing your personal data to answer to your questions and fulfil your requests. I need some info on garmin maps/cards, just bought 2 93sv plus units and a garmin trolling motor and want to upgrade the maps to equal my platinum card I have on a humminbird. can I do this without having to spend 400.00 on cards to the 2 units? can I download just texas and oklahoma without spending 400.00? 7:06:02 AM Serena B If you have a Garmin chartplotter, I kindly ask you to contact Garmin directly. Currently Navionics charts are not compatible with Garmin GPS chartplotters 7:08:42 AM Me you might want to go look at the navionics compatibility listings, garmin owns navionics. 7:10:00 AM
Hello allan,
You can visit lakes.garmin.com to see what lakes we cover and in what capacity. The G3 Lakevu Ultra will have some lakes with Satellite imagery among other features. Our new G3 charts have some Navionics data implemented, and that data will increase as we continue to update the charts year to year. But no the Navionics specific charts are not compatible with Garmin devices.
they have the lakes but not the extras my platinum card had, that is what I wanted to upgrade to.
got me confused now, the navionics site shows garmin under cards, lakevu g3 ultra was what I was looking at. or am I missing something on my loaded maps? sat overlay avail for instance? just got these units so not familiar with all the stuff yet.
thanks

Hello Allan,
The Navionics agent was correct when telling you that their charts will not work on Garmin chart plotters. You need a Garmin chart for your units. You are wanting to get Lakes in OK, and Texas. Your units the 93sv have built in lake charts. Have you powered the units on to see if they already have those lakes covered. You can also review this website
