I am trying to enter my unlock code but MapSource is unable to start the unlock wizard. How do I fix this?
Some versions of MapSource had a problem with the unlock wizard. Download the latest version of MapSource from
here,
install it and the unlock wizard should now work.
I have installed OZtopo on the PC but in MapSource it says 'Map Detail Locked'
near the zoom scale in the bottom right corner and it does not display detailed
roads. What is the problem?
You do not have a valid unlock code entered in your MapSource PC software
In MapSource v6.14.1 or later, select:
Utilities (top)
Manage Map Products
Unlock Region (rear tab)
Add
Type in your OZtopo 25 digit unlock code
OK
Close
On my GPS it says 'Cannot Unlock Maps'. What is the problem?
You do not have a valid unlock code in your map file on the GPS.
For example if you insert your card into another person's GPS then you will get
this message and the maps will not be usable. Maps are unlocked for one GPS
only.
If these maps are meant to be unlocked for your GPS then ensure that you have
entered your unlock code into your MapSource software and then reload the GPS or
memory card.
I currently own a MapSource product, what version is
needed for OZtopo?
We have tested OZtopo V2.1 with MapSource V6.13.7 and later. However we
recommend upgrading to the latest version of MapSource which is available from
here
What maps do I have on my Nuvi?
You can check which maps are in your nuvi by going to the menu page,
Spanner, Map, Map Info
You should see:

- OZtopo V2.1 Roads
- OZtopo V2.1 10m Contours
- City Navigator Australia (standard maps)
If all boxes are ticked then City Navigator and 10m Contours will be displayed.
10m Contours is a transparent map and will display on top of City Navigator (or
any other map)
To display OZtopo V2.1 Roads you need to un-tick City Navigator.
Please note: with OZtopo V2.1 Roads selected the GPS will not look up addresses
or perform 'turn by turn' auto routing. If you are in a flat area then very few contour lines will be displayed
How do I display the OZtopo V2.1 maps on my nuvi or zumo ?
Go to the menu page;
Spanner, Map, Map Info
Untick City Navigator
OZtopo V2.1 Roads and OZtopo V2.1 10m Contours will then display

Please note: with City Navigator unticked the GPS will not look up addresses
or perform 'turn by turn' auto routing
If you are in a flat area then very few contour lines will display
How do I turn off contours on my handheld but still leave the
Roads and Tracks showing? (eTrex Legend C, GPSmap 60Cx 60CSx & 76Cx etc)
Go to the map page,
Press Menu,
Setup Map,
scroll to "I" (information option) using left and right rocker keys
Press Menu,
choose Hide OZtopo 10m to turn off contours,
choose Show OZtopo 10M to turn on 10m contours
I am getting odd errors in MapSource when I try to load OZtopo
(combined map) to my GPS?
Loading the combined map to your GPS is not possible.
Please run C:\Program Files\OZtopo V2.1\OZtopo Separate 2-1.exe
to separate the 2 layers and load them as per the steps below
I have had my GPS swapped under warranty or replaced outside
of warranty. Can I transfer OZtopo to another unit?
Yes. If the unit is replaced under warranty or exchanged then please supply the job
number from Garmin to GPSOZ. GPSOZ will confirm this with Garmin, then issue a
new unlock code.
I have sold my GPS unit. Can I transfer OZtopo to another unit?
No. As with other mapping products, eg Garmin's City Navigator, your unlock code is
tied to your unit.
I have had my GPS unit stolen with OZtopo loaded. Can I
transfer OZtopo to another unit?
No. If the unit is stolen then OZtopo is lost just like any other accessory, cables,
case, and other mapping products eg Garmin's City Navigator. If your unit is
insured, then please include the value of OZtopo when making a claim.
How do I load OZtopo to my Garmin GPS or memory card?
Start the MapSource program on the PC then;
Ensure that you have entered your OZtopo unlock code (see above)
To load the maps you will then need to:
select the Map Tool (odd shaped rectangle)
select all the map segments you want from OZtopo V2.1 Roads
change to OZtopo V2.1 10m Contours (drop down box in top left)
select all the map segments you want from OZtopo V2.1 10m Contours
'send to device' (GPS with arrow towards it)
MapSource will build an index file on the PC, then build a single map file and
then load this map file to the GPS. This may take 60+ minutes depending on your
PC.
For a video overview, see our video
here.
When running MapSource on my PC, I cannot see contours and
roads at the same time
The drop down list at the upper left of the MapSource window only contains the
following entries:
City Navigator Australia NT 2009
No Map
OZtopo V2.1 10m contours
OZtopo V2.1 Roads
Trip and Waypoint Manager v5
(or similar display)
Did I do something wrong in installing the OZtopo V2.1 DVD to miss out on the "combined layer" ?
No nothing wrong. The standard
installation gives you what you have seen, two layers, Contours and Roads.
For the combined layer there are two options;
1. run C:\Program Files\OZtopo V2.1\OZtopo Combined 2-1.exe
or
2. run the install procedure again and select "Alternative
installation options" then "Combined Layer - for PC use only'
The drop down list at the upper left of the MapSource window should now contain the following entries:
City Navigator Australia NT 2009
No Map
OZtopo V2.1
Trip and Waypoint Manager v5
(or similar display)
Select OZtopo V2.1 to displayed the combined contour and road layers.
