You can selectively turn off the maps loaded onto your GPS device per instructions at link below. With multiple maps overlayed on the devices, it is possible that you will have a cluttered display. This completes the process for getting maps onto your GPS. Transfer map from BaseCamp onto GPS, per instructions here: The computer should pop a screen saying something like “new device found.” See GPS instructions for location of plug on your model.īefore going to the next step, give computer a few seconds to identify the GPS Device. Plug in GPS device into computer using USB cable included in box.Load Map onto GPS device using instructions at link below. Open Map in BaseCamp, per instructions here: Make sure BaseCamp is NOT running when you “run” the map. ![]() ![]() You will then need to “run” the map at the end of the download (screen pops-up, click to proceed). in link at immediately above) to your PC. I have used ones from here:Īfter downloading BaseCamp to your PC, here is the multistep process of getting the map from a website such as to your device.ĭownload map (e.g. Garmin sells maps, but there are many free maps. Thankfully this happens automatically after you give the loader permission. This is legitimate and will not harm your PC. When you download BaseCamp to your PC and run it for the first time, the installer may say you need to install Microsoft. If you have a MAC, poke around the Garmin website for the correct link. Here is the link to can download Basecamp to your PC: BaseCamp looks like it was designed by the Department of Agriculture in 1956. The conduit on your PC is an application from Garmin called BaseCamp. You then transfer the maps from the PC via a USB cable onto the GPS device. Maps are downloaded from the internet to a PC (or Mac). To do this successfully several things need to converge, and unfortunately there are gaps along the path. The way to get maps onto the device is circuitous and obscure-a nightmare really. It is possible to overlay maps-for instance road maps and oil pipeline maps-and have them appear on the device like tracing paper. You need to download maps onto the device. For instance, you may use it for hiking trails, whereas an employee for an oil company may use it for locating underground pipelines. The reason for this is the device may be used for different purposes. It does not have hiking trails downloaded to it. Also, I suggest you print an extra copy of the quick-start instructions and bring them with you when you hike.Īs shipped from the factory, the device itself is a raw device. I suggest you play with the device at home with the manual to get used to it. A word of advice: check to see you can read the maps when you are at home not lost on the trail.įor the Garmin eTrex 20, the user experience sucks. The last thing hikers need is a false sense of security. You would have thought Garmin would have blocked this. The only problem is that the device could not read the downloaded maps. I bought a 64 megabyte card, installed it in the eTrex 20, and was able to download the maps. The eTrex 20 only works with cards only up to 32 megabytes, though the GPS physically accepts larger cards. ![]() Although these instructions are for my configuration, they should be a useful guide for your particular PC/GPS combination.Īlso, I suggest adding an SD card to your GPS-the largest one that the device will accept. In addition to my eTrex 20, I have a PC running Windows 7. The eTrex 20 is a reasonable selection given the range of horrible choices of hiking GPS systems. I have one for myself, and I recently bought my daughter one. Since I have two Garmin eTrex 20 units, I must have masochistic tendencies. Essentially, the process is a Kafkaeqque nightmare with many disconnects. In principal, these should work for other hiking GPS systems. Here are instructions for downloading maps from the web onto a Garmin GPS. The map could be copied to the SD card much more quickly by taking it out of the GPS and using a separate SD card writer, but it hardly seems worth the effort. However, a map of that size takes about 20 minutes to download to my PC, and a further 20 minutes or so to copy to the SD card in the GPS. I have the whole of the British Isles (from ) on my Etrex 30, and there is still plenty of memory left. The Etrex 20 has plenty of internal memory, which can be further expanded by fitting a micro-SD card, so you don't need to keep the downloaded map small unless you are concerned about download times. The map will then be available, and probably enabled by default, on the Map page of the GPS. Copy the extracted '.img' file to the \Garmin directory on the GPS, either on the device itself or on its SD card if you have fitted one. The website recommended by neuhausr, and probably most other websites, will allow you to download a zip file from which you can extract a '.img' file.
