1. How may I download the maps?
Answer: If you wish to download maps, we request a donation to assist in
covering our internet costs. All donors of $50.00 or more will receive an
email acknowledging their donations and will receive their own personal
logins to the map download section.
All Rotweilermaps.com mapsets use MapSource and/or BaseCamp for viewing maps on
your Windows-based PC computer and for downloading to your GPSr. A Mac-compatible
installer is also avilable for most maps.
Please note that in some areas, with certain Internet Service Providers,
some members have reports issues with downloading the larger maps. Please
be assured that is not the issue with our site, but regardless, we will do
all we can to assist you if you are having problems. Problems may also
occur when using MicroSoft's Internet Explorer and attempting to download
a mapset, a "feature" of their software. We therefore recommend using
FireFox or other browser.
2. There are many maps. Which mapsets are recommended?
Answer: That is entirely your decision. While the installation of mapsets
that duplicated areas caused indexing problems, this is no longer an
issue with the new builds constructed with the latest version of cGPSMapper.
Regardless of which maps you install into MapSource and/or BaseCamp, we strongly
suggest you do not duplicate areas when installing maps to your GPSr. This
will obviously result in having duplicate POIs, etc (rather common sense, no?).
3. Are the mapsets routing on all Garmin GPSrs?
Answer: All mapsets provide full routing on all Garmin NT compatible GPSrs
with that capability. The maps will not work on old versions of the StreetPilot,
GPS10, iQue as they do not permit loading of custom new technology maps.
They are have been reported to work very well on GPS-enabled smartphone
devices operating Garmin Mobile (see Garmin's XT page at
https://buy.garmin.com/shop/shop.do?pID=11413 for a list of compatible
devices). Garmin state on their site that they now also have software to
run Garmin compatible maps on iPhone and Blackberry.
All mapsets currently under developement will also be fully routing
on all Garmin Units with routing capabilities, including voice (spoken turn
instructions) on all units with that capability.
The maps will route on your computer using Garmin's MapSource and/or BaseCamp
as well as on your GPSr.
4. Do these maps provide full searching capability on the GPSr?
Answer: Yes. With the latest versions of the maps, all mapsets provide
full searching ("Find") capability for POIs (Points of Interest), roads, etc,
in accordance with Garmin standards.
5. Are the City maps [like Chiang Mai, Bangkok, etc] different than the larger map-
set of All Thailand?
Answer: Yes and No. While they have exactly the same level of accuracy as
the maps for those Cities contained in the larger mapsets, these smaller
map-sets are aimed specifically at tourists in the major destinations of
Bangkok and Chiang Mai [and really useful for GPSrs with reduced memory!].
Some of the smaller regional maps have had further development discontinued.
The South Thailand Tourist Edition mapset emphasizes areas and points-of-
interest of particular interest to tourists and visitors to the region.
6. Are the map-sets compatible with all Garmin units [for example, the 60, eTrex, or
Answer: Yes, with limits. They have been specifically tested on the most recent
GPSrs. The maps will not work on old versions of the StreetPilot, GPS10, iQue,
or very old eTrex's, 60's and 76's as they do not permit loading of NT maps. If
in doubt about your model, please ask or check your manual to see if your model
if campatible with NT-format maps (most manufactured since 2007 are...).
7. Why do the maps sometimes look strange inside MapSource or BaseCamp?
Answer: All mapsets may look different in MapSource and/or BaseCamp than
they will in your GPSr. To get a better look at what it will look like actually
installed in your GPSr, zoom in close to the map and ensure the detail level in
MapSource or BaseCamp is set to "Highest". They will look even better on your GPSr
since MapSource and/or BaseCamp somewhat distort the view to make it more legible on
8. What is the difference between the "No Customization" and "Original Roads" options
Answer: The "No Customization" option during installation of any of the Mapset
installers installs the default set of "views" (how the maps look on your GPSr).
"Original Roads" installs the same set of customized views as displayed in
MapSource to your GPSr. SOME Garmin GPSr units do not like this and balk.
There seems to be no way of determining in advance which units accept and
which do NOT.
If this happens, just un-install the mapset and re-install it with the "No
9. How do I install Rotweiler maps to a Mac?
Answer: Before viewing maps on your computer or transferring them to your Garmin GPSr,
you must install Garmin Roadtrip for Mac on your computer. You can download this
program free-of-charge from Garmin's website at the following address:
The Mac Installer mapset of your choice you downloaded from Rotweilermaps.com is
contained in a zip file. Unzip it to see the contents After Roadtrip or MapInstall
have been installed you can install Rotweiler maps simply by double clicking on the
map file (the file will have the map's area name - such as "Thailand" followed
To view the maps or transfer them to your Garmin GPSr, plug your Garmin into your
computer, then open Garmin Roadtrip. Roadtrip also permits you to view the map(s),
search for points of interest (POI's) and get driving instructions between two points.
Click on the portions of the map you wish to install on your GPSr and click on the
"Send Maps" button. The map(s) is now ready to use in your GPSr.
10. How do I install the map-sets on my GPSr?
Answer: If you are using the installers and use MapSource to connect to your GPSr,
then use the standard MapSource method.
Ensure MapSource is installed on your computer. Run the mapset installer.
You will then be able to see all of the map in Mapsource. Go toward or
away from the map so that you can see the entire mapset in MapSource.
Select the MapTool (or click Tools > Map) and click anwhere on the map you
wish to install. The map you just clicked will change color and appear in
the left panel under the tab "Maps". You can repeat this process for as many
maps as you wish, whether from the same map set or from different ones (selecting
OTHER mapsets from the "Select a Product" section just under the MapSource menu.
For example, you may wish to have the maps of Myanmar, Laos, and only the
northern-most parts of Thailand on your Garmin GPSr.
Make sure that your GPSr is connected to the computer. Then click
"Transfer > Send to Device > selecting your GPSr. After the Transfer is complete,
you are done and the maps will display on your GPSr.
If you do not have MapSource (a proprietary Garmin product that is not available
unless you have previously purchased and installed a Garmin map product, or own
a GPSr that Garmin decided to provide a copy of MapSource with), you can either
purchase a copy from Garmin Technical Support (send them an email - they may
even send you a complimentary copy if you recently purchased and registered a
unit, although this is highly unlikely). More information on the installation
of MapSource and options therefore are found on the "MapSource" page linked
from the "Our Maps" page. That page also provides links for additional
materials from Garmin on how to use MapSource.
All custom map-sets are uploaded to your GPSr's SD card as GMAPSUPP.IMG files.
In most Garmin GPS units, custom maps are located in the card's X:/Garmin
folder (where X represents the drive letter of the card). Please note that each
time you send maps to your Garmin's SD Card, it WILL overwrite what is already
11. Can these maps be installed and used from a Mac?
Answer: Yes. The software is different (Garmin has not released a Mac version of
MapSource to date, but does have other software available for that purpose).
Detailed information on the Mac programs for Garmin maps is available from:
MapInstall for Mac:
RoadTrip for Mac:
MapConverter for Windows:
Communicator Plugin for Mac:
If you still have problems installing your Rotweiler maps into your Mac,
please feel free to contact us - we will do all we can to assist you.
12. Are the maps on the site updated? How often?
Answer: The Thailand mapset is updated at least twice a year, but usually more
frequently as new information becomes available. Others are updated at least
once a year but again, usually more frequently.
13. How do I update a mapset to a later version?
Answer: If installing a minor update (with the same version number), you CAN just
install the update over the existing map.
When installing a new version (as from Ver. 3 to Ver. 4), we recommend
strongly that you remove earlier versions first before installing the new
one. Removal of mapsets is simple - open Control Console (or your equivalent,
depending on which operating system you use), click on "Add/Remove Programs,
and remove the selected mapset before installing the new update.
14. Why do strange lines that look like roads sometimes appear on the maps?
Answer: Garmin GPSr's are provided with a so-called "Background Map". These
are VERY general maps intended to provide SOME information even when you do
not have the maps installed for the area you are currently viewing.
In some cases, these "Background Maps" CAN show through the detailed maps and
make the view confusing.
WARNING - follow instructions to the letter. If you feel this may be too
difficult for you, do not attempt unless you know that you are doing!
We recommend you disable the background map (it is pretty well useless anyway)
by connecting your unit to your computer, Open Windows Explorer and go to your GPS
units' root folder. You may have to disable "Hide protected operating system files'
by clicking - in Windows Explorer, Tools, View - and unchecking the entry noted
above. The go to the "root folder and rename the file "gmapbmap.img" to anything you
want but that you will remember in case you want it back later. Note: in some models,
the file will be located in the ".System" subfolder.
15. Can map users contribute to the maps by submitting POIs, tracks, corrections, etc?
Answer: Of course - that is very much requested and in fact required if we are to
continue improving and updating the maps. A link for submitting uploads is
provided in your personal download page.
Please note that there are many different ways to collect tracks (only one
of which is actually useful to us!). Please ensure that you have configured
your GPSr correctly, as follows:
· Set recording interval = Time, 1 second
· Set Locked-On-Road = OFF
· Please include roadway/street NAMES if possible!
For points of interest (POIs), save the POI type and NAME as well. Detailed
information is available at the MalSing Mappers Wikipaedia, which is at
16. Comments by the Map-Makers: We have received a number of emails from map-users
commenting about variances between our maps and their own personal observations of
Coastlines (and the same applies to a lesser extent to city boundaries, rivers, etc)
are very difficult to map. One oberver's "coast" may be another's "rocks in the water".
Is a beach the coastline? If so, the waterline or the top of the beach? At low tide or
high tide. And so on.
In most cases, we have adopted the "mapping standard" for our maps. Coastlines are
headlands, not beaches or rock out-croppings. Sometimes our data is just too in-exact
to make a good decision, regardless of which one we make. Finally, given that
most of us are more interested in the roads and points of interest, we have made a
really simple decision - if alternatives exist, we just pick one. :-)
And so, the moral of the story is - these are not marine-certified maps!
