Hello,
This summer I’ve used to track my road (Highway) with 2 Venus devices (Ekrano and Cerbo) Both with the 3.50.15 Large Beta OS and Globalsat BU-353 GPS usb receiver.
I’m driving @70km/h … but the track is incomplete.
What is the Victron GPS tracking/recording level ? (the weather was clear all the raod)
The logging interval is set in the Settings> VRM online portal menu on your GX device. It defaults to 15 minutes which will give a poor track, set it to 1 minute. Also you should install an SD card to make sure the device saves updates if mobile signal is lost.
