Garmin Etrex 20 and National Geographic TOP maps?

Former Member over 10 years ago

How do I add National Geographic TOPO maps onto my Garmin Etrex 20? I had a Magellan Triton before purchasing the Etrex 20. I paid for a subscription to National Geographic TOPO maps and I could download thru the Magellan Vantage Point software. The maps are saved as a .RMP file format. I can't figure out how to convert them to work with the Basecamp software. I have searched the Internet but am coming up empty handed. Why is this so complicated? Anyone have any ideas?
Thanks,
Bob

Well it's probably because those maps work with a Magellan and not a Garmin. Someone may know different though.

Hi,

The only way that you can use NatGeo maps is to save the maps as a jpg file. Once in the JPG format, you can use some software to convert them into Kmz file and then upload to the your Etrex 20. Warning, Garmin limits the Customs Maps to 100 tiles. I don't know any program that will convert RMP type to IMG.

hope it helps, Reinhard

Thanks. Sorry for this stupid question...but what is a tile? With the popularity of National Geographic topo maps, I can't believe they don't make them for Garmin. I signed up for All Trails Pro because they have the Nat Geo maps now but you can only download a GPX file.

One tile is one Jpg Map segment that measures 1024 x 1024. Here is a link for more info: http://www.garmin.com/us/products/onthetrail/custommaps..

Thanks. I tried to download the My Trails-High Quality Trail and POI Maps Map from the GPS file depot but I don't see it on my Basecamp software. I ran the installer, I can see that it created a folder with a bunch of .img files but I don't see it in Basecamp. I tried to import them but when I browse to the folder withing Basecamp, its empty. Any ideas?
