>>994627>I honestly don't know much (Pretty much clueless) because I only started searching them up today, I need to do a bit more research on this area also.Definitely - there's a lot of options and features out there. Familiarize yourself with what's out there, figure out what you need and what'd be nice, figure out a reasonable budget, and go from there.
>As far as I know CityNav and Topo are maps? Might be wrong on that one.Correct. Some now ship with topo maps loaded, CityNavigator is what the car GPS's use. Your handheld can take and use that mapset.
BlueChart maps are for marine navigation. That map has depth charts, navaids/buoys, etc.
>Can you give me a very quick rundown on how they work? I imagine that you install and put them on the device through a PC.Yeah, pretty much. BaseCamp is Garmin's software for communicating with the GPS. Wraps everything into one package - waypoints/routes/tracks into and out of the GPS, file management, firmware upgrades, map installations, etc.
MapManager/MapInstall are Garmin's older software tools for getting map data to the GPS.
Personally I'd try out BaseCamp, since that's currently-supported software.
Garmin's map install process is kind of clunky. If you buy the map on disc, you'll have one step where you load the maps from disc onto your computer (that's what MapManager is for).
This typically installs the entire map area onto your computer.
The second step is selecting the map tiles (sections of that entire map you just installed) then packaging them and moving it to the GPS. That's what MapInstall does.
BaseCamp should incorporate both those tools, and I'd hope they've made the process a bit simpler since I did it.
Once it's on the GPS, it should just show up on the map page. There's some configuration you can do to show/hide layers, dive into the menu and figure out what does what in there.
