Hi, I have four ST70 heads connected to a STNG backbone and interfaced to a Garmin chart plotter, the original Raymarine MFD expired. Is there anyway to update the ST70 heads software/firmware without a Raymarine MFD?
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
