GPX: Tracks, Routes & Waypoints

• Line Appearance — line thickness, opacity and direction-arrow size, with a live preview on the map as you drag each slider; and under Line Coloring, Unpaved Dashes (a dashed overlay over the unpaved parts of a line that run 250 m or more, coloured by how rough they are; a stretch with no road data under it is never dashed), Slope Coloring (the whole line recoloured by gradient steepness) and Overlap Arrows (direction markers where a line crosses itself). All of it shapes the navigation line too.
• Pins on the Line — Pin Size (waypoint pins, and with them the navigation's turn icons and speed-limit roundels), Show Route Points, Distance Pins (a marker every 25 / 50 / 100 / 250 / 500 km or mi along each track and route, each one labelled with the distance it stands for; where they would overlap — zoomed out, or where several tracks run side by side — only those with room show, the round distances first, and the rest come back as you zoom in) and, under Pins Ahead, Steep Section Pins, Unpaved Section Pins and Speed Limit Change Pins. Those three are live: they appear only while you are actually following a line — riding on (or near) it — and mark the next few ahead of your position rather than every one in the file, so the map stays readable. Steep pins mark sections at 15% or steeper, with an arrow for up or down and a colour for how steep. Unpaved pins mark the start of each dashed unpaved stretch. The Waypoint Labels group (Show Waypoint Labels, Waypoint Label Size, Hide Waypoint Labels Beyond) is marked GPX only.
• Progress Card — which rows the progress card shows: Distance & ETA to End (the end of the track, route or navigation), Next Waypoint Progress, Next 3 Waypoints (off by default: up to three upcoming waypoints on the card instead of only the next one, in landscape as the card has room) and Compact Progress (swap the full card for a small distance-and-ETA pill so more of the map stays visible; tapping the pill opens the same things a tap on the full card does). The last three are marked GPX only — navigating to a point always keeps the full card, with its turn banner and Navigation Options. Your Priority Waypoints need no switch: they always get their own lines under the waypoint rows, up to three in landscape as the card has room, the next one in portrait.
• Off-Route & Re-Routing — how the You are off route dialog behaves when you leave a calculated route. Switch the dialog off entirely and pick the method DMD Next applies silently instead (ReRoute To Line, ReRoute To Next Point or Do Not Reroute), set how long the dialog waits before confirming on its own (5–30 s), choose which option it pre-selects (your last answer, or a fixed one), and decide whether route dialogs capture the remote controller (Always, Never, or Once per navigation). The panel says it up front: navigating to a single destination always re-routes automatically; these options govern GPX routes and multi-stop navigations. The options themselves are explained under Off-Route Choices.
• GPX Files Only — the rows a navigation never touches: Track Navigation with its curve alerts; Color on Import, that is Override Track Color / Override Route Color (switch either on, pick a colour, and every track (or route) in a GPX file gets that colour as the file loads, in place of whatever colour the file itself carries — it applies to files loaded from then on; for files already on the map use Set Colour For All instead; nothing is lost, Reset on a line hands the file's own colour straight back); and, under HUB Sync, Auto-sync edits to HUB and Help the planner learn better routes (see Help the Planner Learn).
• Colour — give a track its own colour, or let a colour mode (surface / slope) take over. A colour set on the HUB comes through too.

What counts as unpaved. The Unpaved Dashes, the Unpaved Section Pins, the paved / unpaved split in Stats and the HUB Planner all use the same rule on the OpenStreetMap tags of each road: a tracktype of grade 2–5 is unpaved; otherwise the surface decides (gravel, dirt, grass, rock, sand, wood… are unpaved; asphalt, concrete, sett, bricks… are paved); a road with no surface tag is unpaved if it is a track, path, bridleway or footway, and paved otherwise. Short blips under 150 m take the surface of the road around them, and where a line leaves the mapped road network it has no surface data at all — left out of the percentages rather than counted either way.
