Recently Suzuki released updated software for the newer Engine Interface Cables that run the .swup software versions 2.9.0 and 3.5.0.
These new versions are 2.9.04 and 3.5.04 and are designed to improve stability and the missing data issues that some people have experienced.
If you have a Suzuki C-10 gauge, you can upload the new software thru that. Or, if you have a Lowrance or Simrad MFD on your network, via that.
Here is a link to the official Suzuki software page where they can be downloaded. Install is easy - Just save the file to a SD card of max 32GB (for loading via Lowrance or Simrad displays) or to a USB stick (for loading via C10).

Insert the card/USB into the device. Using the device menu, find the files menu, open it and find the SD card/USB, then locate the update file, highlight it and upload. Progress bar while it uploads. Done. (Note if you run twin engines, should update 1 interface at a time by turning one key off.)
Suzuki has also released a new “Connect” interface cable that allows full interface and functionality with Lowrance or Simrad displays without needing a C10 on the network. In other words, you can have all engine data on a compatible Lowrance or Simrad display, and get full engine fault codes, service reminders and alarms. No gauges needed.
For twin engines, only one engine needs to have the Connect cable connected, the other uses a normal interface cable.
Any questions - fire away, I will try to assist.
