I have been using my OR300 on the USB port on my laptop for nearly 14 months without a problem - actually one of the few things which have not gone 'bad' on that computer. With all the non-USB problems I have had with this Gateway; all indications are even a $900 Gateway computer is cheeply built junk.

Did you look at these tutorials at gpsfiledepot? http://www.gpsfiledepot.com/tutorials/how-to-install-mapsource-if-it-didnt-come-with-your-gps/ http://www.gpsfiledepot.com/tutorials/how-to-open-maps-in-mapsource/ http://www.gpsfiledepot.com/tutorials/how-to-load-maps-on-my-garmin-gps-unit/ Follow the instructions EXACTLY IN ORDER to install-mapsource. You may also have to uninstall the LAtopo before installing mapsource. Downloading BaseCamp from Garmin's website may be an easier way to go. Install LAtopo (and other mapsets) with MapSource closed; otherwise it will not see the new mapsets until it is closed and restarded.

Check the mapsets for Arizona at gpsfiledepot.

It would be easier to answer if you had said which mapset in on the unit and what you are looking for in the way of data on the maps. Were you are located would also help. Garmin's CityNavigator is updated ever 3 months; but check their website to see if you can preview your area as the data still may not be current. Their 100K topo product varies in age depending on location; West Coast was first (about 2 years ago) and they progressed eastward - but likely still to old for your road. Check their website for a preview. Census is now releasing their data for 2010. The previous version was 2009. It is unlikely that any of the free mapsets would have your road. OpenStreetMap uses even older Census data; however, someone might have sent them the info on your road. If not, you could 'GPS' the road and send the info to them for inclusion. You could also 'GPS' the road and learn how to put it into an overlay/transparent mapset which would display with the mapset already on your GPSr.

What mapset are you using for the transportation info?

Look at Garmin's site in more detail. Wisconsin eastward is on the Northeast DVD. MN in on the NorthCentral DVD. Their graphic indicates Isle Royal, MI is on neither.

The mapsets at gpsfiledepot are not routable. As Chrysalides posted, the ones at garmin.na1400.info are.

If your internet service is 160K/sec that equates to about 149 minutes or about 2 1/2 hours. Can not help on the unlock issue, however, remember some post earlier this year were a cannot unlock message was given on a product that was not locked, but this may have been for the DVD version.

OSM - the seed was Census TIGER date 2006 or earlier. Does not have address search, if that matters to you. Also no contours - you can use the contour line overlay matsets from gpsfiledepot. DEM - Digital elevation data. This will give a 3D view of the land's surface. If you can not visualize the surface from contour lines you may want a Garmin mapset which includes this. I do not think CN does. None Garmin maps do not as how to do so has not been reversed engineered. You have to use MapSource or BaseCamp to access the mapsets and select some or all quads/tiles to send to the mirco memory card (or GPSr's internal memory). made. You will also have to do the same for any Garmin product on DVD.

Depends on the GPSr. With the newer models (CO, OR, DK, 52, 78) simply delete each renamed mapset. Or with older models or a single gmapsupp.img file (if you did not rename each as it was uploaded) you will have to MS/BC to recreate what was sent to the GPSr by not including those maps you wish to remove.

It is inadvisable to add anything to a Garmin pre-recorded micro memory card. The Garmin mapset may become corrupted and Garmin will not replace it. If you want to use CN on more than one GPSr, you can move the pre-recorded card from one GPSr to the other. With other formats you would need to purchase a copy for each GPSr. If you go the pre-recorded route, you have some room on the GPSr's internal memory for other data, i.e. topo. Unless you need the data imediately, download is generally considered the least flexable of the three. There have been posts from those who did so and regreted it. DVD allows you to send all or some of the mapset to available internal memory or a micro memory card. CN will be locked to one GPSr, however you can also have other mapsets on your micro memory card. CN and a topo mapset (Garmin or other) will not be displayed at the same time. CN has priority of display. You will have to disable it to see the topo. gpsfiledepot has overlay/transparent contour line mapsets which will display with CN, however the hydro in CN is very basic.

Look at gpsfiledepot. Georgia Topo. Don't need contour lines, US Planimetric - South East. File sizes average 1 to 2 Mb. Use MapSource or BaseCamp to select the quads of interest and only transfer those to the GPSr.

I have not looked at the file; however according to the cGPSmapper User Manual, ~[0x1f] is a valid special code for object labels.

No. Each GPSr company has their own propriatery format. The map data from one company is not usable in the GPSr from another company.

Try using BaseCamp; it is a free download from Garmin.

How many mapsets are in the 7.3GB total? There was a post a week or two ago stating there was a 10 mapset limit per sortarge 'device'. I ran a test on my OR300 and posted my findings of not having a problem with 17 on a micro memory card.

With the detail level set to normal, most mapsets will display the full range of features when the GPSr display is zoomed in to the 500-800' level. Unlike MS/BC the GPSr will not center on an enabled mapset(s); you need to pan to the area you uploaded if you are not actually in that area. Some info on which mapset(s) would be helpful to someone responding - also consider asking on the gpsfiledepot forums.

I just tested this on my OR300 with 17 different mapsets in 17 renamed .img files on the micro memory card. All 17 are listed in individual enable/disable boxes, as is the basemap on the OR300's internal memory.

That unit is also limited to a total of 2025 quads/tiles.

In a PC environment, you need to have MapSource or BaseCamp installed on your computer. You then run the .exe file you downloaded from gpsfiledepot; this will make the necessary changes to the computer's registery so MS?BC can 'see' the mapset. Then in MS/BC select some or all of the quads/tiles and send them to the GPSr, or micro memory card in a card reader. See the tutorial: http://www.gpsfiledepot.com/tutorials/how-...s-in-mapsource/

With things like that and not being able to set a waypoint at other than the current location, they seam to be sending a strong signal that the decision makers in their design staff have never used a GPSr.

Compare a paper map at 1:100000 with one at 1:24000. The 1:24000 will use about 4 by 4 times more space to show the features in an area; therefore it can show smaller/less important/more detailed features and more detail in a each feature. Depends on what detail and features you feel you need for what you wish to use it for and how large an area you feel you always need available. The more detail, the more files and memory those files will require. You can always start with the free topos (with detail similiar to a 24k) on gpsfiledepot. If they do not have some of the 'features' Garmin has in their products, get Garmin's 24k or 100k product depending on your buget and extent of area you need.

The files do not transfer to the GPSr; they are 'read' by the GPSr from the micro memory card. Yes, you are supposed to be able to 'read' the Garmin prerecorded micro memory cards in more than one GPSr; obviously only the one which has the card in it.

As I said in my 11/22 12:36 post, 'Garmin has their software assigning the names of the first 3 or 4 quad/tiles in the selected list to both/all mapsets' even if they are not in that mapset. Until Garmin changes that, we have to live with it, annoying as it may be. As also mentioned the workaround is to select from one mapset, send the data to the GPSr, then rename the gmapsupp.img file. Repeat for each mapset you want on the GPSr/micro memory card.
