Review trip routes

A route map appears on the trip detail screen whenever GPS coordinate samples were recorded. This includes automatic trips and live manual recordings.

Past drives entered by address (without live recording) do not have GPS breadcrumb data and will not show a GPS route map—only start and end pin markers.

On the device, routes may have many hundreds of GPS samples for a long drive. When the trip is synced to the cloud, the coordinate sequence is downsampled to a maximum of **80 points** using a distance-based reduction algorithm.

This means the cloud-synced route is an approximation of the full on-device route. The overall shape of the route is preserved, but fine-grained detail (e.g. a gentle curve through a roundabout) may be simplified.

The **distance calculation is performed on the device before downsampling**—the 80-point limit does not affect the recorded trip distance.

Gaps in the route line indicate periods with no usable GPS samples—common in tunnels or underground structures.

A very jagged or erratic-looking route line usually indicates low GPS accuracy. Check whether the trip has a **Low GPS Accuracy** flag.

Routes with very few points (fewer than ~5) may not render a visible path—the map will show start and end pins only.
