[JB] ST70 update

[Jules - Raymarine - Moderator]

Hi Deekay911,

Welcome to the forum.

It is not possible to update the firmware on the ST70s without a Raymarine MFD. Since you have a STng network already, best option would be to borrow a Raymarine MFD from someone willing to loan it to you. Alternatively, you can engage the services of an Authorized Raymarine Service dealer to come to your vessel.

Please use the Dealer Locator here https://www.raymarine.com/buy/find-a-dealer.html to find the closest to you.

Happy boating

Kind regards
Jules
