You can do it with a 60CSX like this. From the map page press the menu button, then right or left arrow to the "i" icon in the circle. That gives me a list of all the individual map sections on my GPS. You can turn them on or off by selecting the map name and pressing enter.
Pressing Menu again lets you turn off an entire map "product" like "Homemade maps" or "City Navigator".
With luck you'll find an analogous solution on your Etrex.
The Etrex Vista is the same as I have several maps created with mkgmap and then have uploaded them via mapsource.
Then in "map setup" bring up the menu and disable/enable the maps as required. Searching POI seems to look at all maps even if they are not enabled.
I did eventually work out his email address and with his help I have and Australian one up now which I just posted in http://forum.openstreetmap.org/viewtopic.php?id=2875
With the help from the keepright creator I have been able to get one up and running for australia.
As it previously only covered Europe you may not have seen it before but will show many map problems like nodes close but not connected, one way streets the go nowhere, non closed areas, and many others.
Not all the checks listed are running yet but hopefully soon.
I want to be able to browse Australia to look for the problems and downloading the data into josm/mapedit is not suitible ( I do use both for various tasks).
The keepright output is perfect so I am trying to contact the owner to see if it can be included or if he can can provide the code to run a Australian server myself but I am having problems working out his email address.
I have been testing the routing maps from mkgmap which is working quite well.
I recent had an issue where the GPS would just suddenly say it cannot route but a few minutes down the road would work again.
Eventually I tracked it down to a large freeway interchange where the ways where not connected but they look like they where.
As the nodes where not in the same location, mapnik did not pick it up as a problem so they are difficult to find and spending a while in the area I found a few more.
What I am suggesting is a method to highlight the last node in a way.
This will show up all the no through roads but also the problem I found as you would not expect a no though road on a freeway.
Just a thought
The total area covered is:
size = 180.0 / Math.pow(2, Zoom Level)
Then as the coordinates in the url are the center of the screen then subtract half the size from for the one set points then add half the size to get the other.
This assumes a square area but is close enough for what I am doing and also JOSM.
FYI, What I am making is a Java App that for a given area, lists all the tags used and the values on those tags. You will then be able to select the object and open it in JOSM and fix what you need and upload. It has an ignore list so tags like "source"
This will make it easier to see everything you have done is spelt correctly.
I got the idea from TagWatch, http://tagwatch.stoecker.eu/, where I saw many typos listed in Australia where I started to fix them, but as it's only updated 3 times a week so I needed to wait for the update to see where I was up to.
If you think it maybe useful I can host is somewhere for download when complete ( Just need to launch JOSM now and set up preferences)
I am trying to extract data for a custom app and the easiest way is to use zoom on the slippymap then use the permalink value to do the extract but I cannot find the formula to do the conversion to a bounding box values.
If someone here could point me in the right direction that would be great.
The database schema version of 16 does not match the expected version of 11.
I had the same problem and downloaded the source for osmosis and it was fixed (you will need to install JDK and ant and make sure that java is in the path before any another).
I assumed the database schema has moved up a few in the version that can be downloaded from svn but the prebuilt version of osmosis has not kept up.
Just got mine running today and is now rendering the tiles
I was checking an area I had completed a while ago and noticed the roads were red instead of orange so I assumed the highway type was wrong but checking it was correct.
The road next to it was the correct color and I noticed the only difference was on the red road was a small padlock next to the way number. I clicked on the lock and it disappeared and the road is now correct.
Not sure where it came from and cannot find and mention of it in the potlatch doc.
I extract the area near my home so I can load it into the GPS to see what I missed but often it just fails with:

I guess the server is having problems as the command is correct as it will work a couple of times a week.
The extract command I am using is:
wget -T 540 -O home.osm http://www.informationfreeway.org/api/0.5/*[bbox=145.2,-38.1,145.4,-37.9]
Is this normal behavior or am I doing something wrong?
I am using JOSM to create the maps at home but when its quiet at work I am using Potlatch as my traces are on the server.
From what I can see as the edit are only put into the map every Wednesday, so until that occurs I cannot download from the server into JOSM and see my edits done with Potlatch until that occurs. The other way works ok.
Is there a way around this or do I need to take the JOSM saves with me?
