Installing onto a Garmin wearable (Fenix etc)
Many Garmin werables, such as their Fenix series of watches, are capable of displaying maps. This page explains how to send the Topo4GPS map from Garmin's BaseCamp software to the wearable device, and assumes you have already followed the instructions on installing both BaseCamp and Topo4GPS on to your PC or Mac.
Sending a Map from BaseCamp to your Garmin Wearable
Garmin wearables such as the Fenix series support custom .img maps
but don't always play nicely with BaseCamp's direct install. The easiest approach is to use a USB flash drive
as a staging area, then copy the resulting map file to your watch.
| 1 |
Insert a USB flash drive into your PC and create a folder on it called Garmin (capital G).
|
|
| 2 |
In BaseCamp, click Maps > Install Maps.
|
|
| 3 |
When prompted for a destination, select your USB flash drive. Click Continue.
|
|
| 4 |
Select the area of NZ you want to send (left-click and drag to select; right-click and drag to deselect). When happy, click Continue then Install.
|
|
| 5 |
Once complete, open the USB drive. Inside the Garmin folder you'll find a file called gmapsupp.img — this is your map.
|
|
| 6 |
Connect your Garmin wearable to your PC via its charging/data cable. It should appear as a removable drive.
|
|
| 7 |
Open the watch's drive and navigate to the Garmin folder (create it if it doesn't exist). Copy gmapsupp.img into this folder. If a gmapsupp.img already exists, back it up first — it will be overwritten.
|
|
| 8 |
Safely eject the watch. Once it restarts, go to Settings > Map > Map Data and enable NZTopo4GPS.
|
|
Note: Wearables have limited storage — you may need to select only the regions you need rather than all of NZ. On some models the map folder may be called Map rather than Garmin — check what already exists on the device.
