There are issues with 4.0. See [Only registered and activated users can see links. ].

While I like the prospect of being able to install a map without having to select all the tiles, Garmin's implementation leaves a lot to be desired. They dumbed the interface down to an unacceptable level. Now, at least from how I understand things, in the advanced options maps that haven't changed are going to get reinstalled with the maps that DO change. It gets worse. If you don't use the advanced options and tell MapInstall to go ahead, it will install every compatible map it can find to your device. What it doesn't say is whether those maps will be individual images or (more likely) one gigantic map image.

Seriously, the old MapInstall interface was perfectly fine, but could have benefited from the following:

1. A simple checklist of compatible maps, allowing the user to select or deselect the maps he or she doesn't wish to be installed. The current rendition is not simple and in fact is quite confusing. You have partial and full maps color coded with a drop-down box offering whether to leave the map as is, to remove it, or to install the full map. Where is the option to NOT install the map at all and not remove the existing map? It's not there.

2. On the map screen, a button to select all tiles on a map set. As presented, going into advanced options by default all the map tiles are selected, which means individually selecting each and every tile and clicking on it to deselect it. I attempted to do a mass deselect of the tiles in a copy of Europe and could not do it, so this is now a really painful process that could have been fixed simply by keeping things the way they were.

3. Each map selected in 1 pops up in sequence, similar to how POI Loader works for POI files. I'm sure there are other ways to do this, but POI Loader already does this and I assume most people are familiar with that software, so having both pieces of software functioning identically is a good thing.

4. Memory size available as a combination of both internal and external memory on each map screen. MapInstall 4.0 DOES implement this, however according to the link to the Garmin Forums, the implementation isn't working properly.

5. A help file would be nice. This here could have eliminated many of these concerns, simply explaining what would happen with selected maps. Do these maps get combined into one large map image? Does the end user get the option to name the file for each map? Does the map get installed regardless of whether it has been actually updated or not?

Unless you are a neophyte Garmin user or unless Garmin actually makes the software usable, I would recommend sticking with MapInstall 3.15.
