General Discussion / Re: real topo maps for garmin?
March 10, 2010, 12:01:46 PM
I am interested in Texas topos. I have downloaded the Texas topo available on here already. The type I am looking for should be shown below. Mapselect has downloads that allow to pick sections of a topo map to download and place on your gps device. Their description are as follows:

Unique, downloadable maps for Endura™ GPS handhelds and XOG™ with U.S. satellite and aerial imagery, enhanced USGS topographic data, and BLM mapping.




So you are saying I may not be able to place them on my Nuvi 550 because of the resolution limitations on it?

General Discussion / real topo maps for garmin?
March 09, 2010, 06:08:20 PM

I am going through the painstaking process of trying to convert my routes, locations, etc that I recently had on my Lowrance XOG so they will work on my new garmin nuvi 550. I believe that I got the "data" file converted alright from the .usr format to one that will work alright in mapsource.

The problem I am having is trying to convert the numerous topo maps which I bought from Lowrance's "mapcreate" to work in the garmin/mapsource. The topo maps from "mapcreate" are basically blown up images of actual topography paper maps, which I prefer since it has detailed writing on paths, etc. An example of what topo maps I am talking about is shown in the link below.

The current topo maps that I have already are labeled for example:

07222009_01-01_EnhancedTopo_29100E3.at5

Are there any custom maps that have this type of topography that I can already download onto my garmin?

If not, how can I convert the .at5 file to something that will work in my garmin?

Thanks for the help guys.

I would appreciate any help you could offer. Please give me layman's terms. I am def a newbie at this. Thanks in advance guys.
