Question: I have a 2019 echomap plus 95sv, preloaded with 2020 maps. With your update card for preloaded maps, would the auto guidance feature be available?
Answer: The Garmin BlueChart g3 update card will ONLY update the preloaded charts that you are using within your Garmin ECHOMAP Plus 95sv. It will not add features that your Garmin ECHOMAP Plus 95sv chartplotter does not already have i.e. Auto Guidance.
If you require Auto Guidance on your Garmin ECHOMAP Plus 95sv you will need to purchase the a new full Garmin BlueChart g3 chart for the water(s) you require.
Auto Guidance used to be a feature found on the premium Garmin BlueChart g3 Vision charts, however it is now also included on the standard Garmin BlueChart g3 charts too.
For chart coverage options you can buy and that all feature Auto Guidance, please see:
‣Garmin BlueChart g3 charts (regular chart coverage only)
‣Garmin BlueChart g3 Vision charts (small chart coverage)
‣Garmin BlueChart g3 Vision charts (regular chart coverage)
‣Garmin BlueChart g3 Vision charts (large chart coverage)
