eTrex sync

Syncing an old Garmin eTrex with modern fitness tracker apps. Yes I could buy a modern device but that seems a bit wasteful.

Needed equipment

• Garmin eTrex 20/30 or simular
• Apple iPad / iPhone
• iPhone / some iPads: Lightning port to USB-A port adapter
• some iPads: USB-C to USB-A
• USB-A to USB-B Mini lead.
• Komoot app installed

set up eTrex (do this once)

• On your eTrex, press back until you get the main menu
• Confirm the following settings
• “Setup” -> “System” -> “USB Mode” -> Select “Garmin”
  • This enables access to the GPX files on the eTrex
• “Setup” -> “Tracks” -> “Auto Archive” -> Select “Daily”
  • This is optional
  • This splits the track up each day which is handy for finding a tour by date
  • If you do more than one tour a day or multi day trips probably best to manage this manually.

Komoot Tour to eTrex

Being able to get a planned tour on your eTrex ready for your ride.

• Plug USB lead between iPad/iPhone & eTrex
• “USB cable detected, Would you like to go to Mass Storage?” select “Yes”
• Open Komoot app
• Profile -> Tours -> Planned
• Tap on the tour you want
• Tap on “…” icon in top right corner
• “Export GPX File”
• “Save to Files”
• Tap the top left “< Name” option till it says “Cancel”
• Scroll to the bottom of the list where hopefully you will see “GARMIN” listed
• tap on “GARMIN” -> “Garmin” -> “GPX”
• tap on “Save” in the top right corner
• unplug the USB lead at both ends
• Power on your eTrex if needed.
• Press back until you get to the main menu
• Select “Track Manager”
• Select the name of the Tour.
• “View Map” -> “Go” (assuming your near the start)
• alternatively select show on map to leave it on your map.

eTrex log to Komoot

Having done your planned tour now you need to see how you did.

• Plug in USB lead between iPad/iPhone & eTrex
• “USB cable detected, Would you like to go to Mass Storage?” select “Yes”
• Open Komoot app
• Profile -> Tours -> tap “+”
• Tap “Import a File (GPX, FIT or TCX)”
• Tap the top left “< Name” option till it says “Cancel”
• Tap on “GARMIN” -> “Garmin” -> “GPX”
• If the ride was today select the “Current” folder and the “Current” file
• If the ride was on a previous day tap the “Archive” folder and select the file of the rides date.
  • Its in YYYY-MM-DD HH.MM.SS Day format
  • The time stamp appears to be at the start of the file in local (not UTC / Zulu) time.
