How to create a custom Map for Garmin GPS Part 1

[traillogger]

Thanks for the great "How to" video. I was able to succesfully creat a map based on a stored track. It is transparent and overlays the base map on my Garmin Quest. However I would like to overlay the track as a polyline on another map I have which contains much more detail. Could you please give me some tips and point me in the right direction, or is this not possible to do?

ibycus314 thank you for this really useful information. Yesterday i made my first test map for my Garmin colorado 400t after watching your video. But i have some questions.

But i don't know how to unlock it, so it doesnt appear as a map on my device. If you know something that can be helpful i will be

Thanks for the information. Basically what I want to do is map out 4x4 trails in relatively uncharted area. Because its not a common use for Nav systems, its hard to find the info I need.

There are a few projects underway in different areas (Google Calgary Trail Maps for an example). But pretty much any 'outdoor' Garmin GPS will do the job you're looking for.

What Garmin unit did you use to gather the data? Do they all do it? Thanks!

You mean the trail data? I used a Garmin 60CS. A lot of them will, although not quite all. Basically, what you need is any GPS that supports a "Tracklog", which is most (although some of the Nuvis don't)
