Welcome to the Raymarine Forum Arvid,

Should the MFD be interfaced to a fishfinder transducer, then depth offset must be configured within the Transducer Set-Up menu of the MFD's Fishfinder application's Set-up menu. When so configured, offset depth reported by the MFD will be repeated by SeaTalk devices within the system (i.e. offset cannot be configured via a repeating devices ... only in the master device). Failure of the system to report as has been specified within this response would be indicative of older software within the system's SeaTalk to SeaTalkng Converter. Regarding the units issue reported for the ST60 Tridata, this is a limitation of the product. Unless acting as a Data master (would require that the associated transducer be connected to the display), units cannot be changed by this product.

Regarding the MFD's SonarChart Live feature, the following prerequesites must be met to utilize the SonarChart Live feature:'
- a Navionics+ chart card having a current Freshest Data Subscription, having additionally been populated with SonarCharts via the Navionics Chart Installer program for the waters being navigated, and having received Freshest Data updates. This chart card must be present within the MFD's memory card reader.
- alternatively, a Navionics Platinum Plus chart card having a current Freshest Data Subscription and having received Freshest Data updates via the Navionics Chart Installer program for the waters being navigated. This chart card must be present within the MFD's memory card reader
- the Chart application's Sonar Logging feature (MENU->PRESENTATION->DEPTHS AND CONTOURS->SONAR LOGS) must be configured ON
- the Chart application's SonarChart Live feature (MENU->PRESENTATION->ADVANCED OPTIONS->SONARCHART LIVE) has been configured ON
- the MFD or system has been interfaced to compatible fishfinder transducer (excluding SideVision transducers).

You may also want to consider configuring the SonarChart to the Very High configuration setting initially.
