Question: Garmin GPS map detail in Colombia, South America Anyone used this GPS or similar in South America? Wondering about map detail and accuracy...
Document: I purchased this item in hopes of using it on my bicycle to travel down many different country roads in my area. The explanations for what this unit does were not clear and the unit did not live up to my expectations. It comes with a base map that tells you basically that you are in North America. I already know this and wanted more detail so I ordered the Maps on DVD recommended by Garmin. These cost an extra $100.
There's only a dozen or 2 roads listed in all of Manhattan. (Other US cities have similar detail.) If you want to do anything interesting, except know the exact coordinates of different points you load, you've got to upgrade the map.PS - "Beast Hunt", one of the included games on the unit, is more fun than I'd like to admit.
Problem solved.Not! There's another problem here: this unit can draw the (useless) basemap pretty quickly, but add a topo map with any level of detail and it takes it ages to draw the map. Not a problem you're thinking? Think about it like this: say you're on the trail and would like to find a stream near you to filter some water from. You can either zoom way out or move the map pointer to your north, south, east and west.
Therefore I had to find a map to make my GPS useful. I looked in the Garmin website to see what maps were compatible to the device (eTrex Venture HC) and the first one recommended was the Garmin City Navigator North America NT ($80.00). I researched this program and it seemed to by what I was looking for. I went ahead and purchased it.
The free software from topografix doesn't work as well as the Garmin software that comes with this GPS but I suspect the non-free topografix software may be a bargain (don't waste money on the amazingly detail-free Garmin world map software). I found the array of 3rd party software options overwhelming.
I've owned my garmin etrex Venture HC for about a month. I read all the critiques about the low detail map but tried it anyway. I wasn't looking for an automotive GPS, I wanted a hiking-flying-fishing-traveling GPS. Without the detailed topo maps this thing was very good for my needs. It would show me what was the next exit on the freeway and what services were there. It gave me speed, altitude, and positional awareness when flying in general aviation aircraft.
The "Enter" button didn't perform well at first but now it seems better. When pressed initially, nothing happened, but now, after a week of use, it seems to work every time it's pressed.Also, in the map view, there's a ring around the position indicator at about 0.20 statute miles. This ring indicates the combined accuracy of the map and the GPS receiver, according to Garmin.
This GPS has been an absolute waste of many an hour trying to load some very expensive maps onto it. Fortunately the unit was a gift and i didn't waste my money on it however i can never tell the ones who did. The only money i through away was on the map. I would never recomend this to anyone.
This is the only GPS I have had and I used it primarily for geocaching. Others have given in depth reviews of accuracy, ease of use, and other aspects of this device, so I won't waste time on them. When it worked it was an adequate entry level GPS for geocaching. However, three days ago while on a week long multistate trip of which geocaching was a primary goal, the device malfunctioned. We were just walking along to the next cache and the screen faded out.
They told me that some of the map sizes are really too big for the device, yet technically the mapping program is compatible with the device. In actuality, however, some areas are not compatible. I would not recommend this product to anyone who actually wants to put large maps on their GPS. Gamin's Costumer Service was very nice though.I was then stuck with a GPS and a mapping software that were useless to me because the area in which I live was too large to put on my GPS.
Answer: Pablo,I have used mine in Colombia, Argentina and Chile.  The accuracy is as good as anywhere else in the world.  The map detail deppends on the map itself.  In Colombia you can get a map from www.micropartes.com it has good detail but also some errors. In Argentina and Chile the maps are very accurate but I don't know the sources of those maps.
