Re Garmin POIs
|I first need to extract campsites.gpi from the 660 and convert it back to a gpx ...
So how do I extract the gpi file and convert it back to gpx and bmp files?
First, you can convert GPI file using the GPI editor
Second, you can simply add new POIs to your local PC POI folder, as explained here
. Use POI Loader to create new POI.GPI file, rename it and copy to your Nuvi.
Hope this helps
