newbie question about ,img files

[Keukasmallies]

First time viewer, first post....

I have a Garmin nuvi, model 260w.  I downloaded nytopo maps in .img format and transferred them to my nuvi (They made themselves a NYTOPO folder).  So far, so good.

Problem is that I can't figure out how to get the nuvi to utilize the topo maps.

Help....

Thanks in advance for your responses

They install on a nüvi like any other mapset, You need MapSource for Windows or RoadTrip for Macintosh. To get MapSource, follow the two steps in this tutorial:

If you have a Macintosh, get RoadTrip here:

Then you can install the maps to your GPS following the instructions here:
