converting .at5 maps to garmin format

TEXN · 03-09-2010, 7:24 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. XOG product updates/support are no longer since Lowrance discontinued it. Bummer. Anyhow. 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. I am pretty sure there is a program of some kind that will make it work. 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.

For example, one of the topo maps is labled:

07222009_01-01_EnhancedTopo_29100E3.at5

So I need to convert the ".at5" format to ??? for it to work in mapsource?

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.
