You might get the best answers in the Geohunter discussion group: http://groups.google.com/group/geohunter Anyway, I also have a Desire and use Geohunter: they are both great. If I understand your question correctly, the large arrow with the green dot points to the cache. The smaller "diamond" with the red end points North, just like in a normal compass. I don't use Find Caches, so I can't help you there. Cheers.

Er... did you get as far as to install the map in Roadtrip? If so, the next step is to use MapInstall to send the map(s) to your Vista. Preferably use a card reader and install the maps directly to the Micro SD card, as this is much faster than the USB connection to the Vista. Cheers.

To directly answer your question: no, JOSM is strictly an OSM editor. In contrast to Potlatch, which is an online editor, JOSM is an offline editor: you download the region you are interested in, make your changes and upload them. You can also use JOSM for private editing purposes. That is, you can edit any OSM file which you have downloaded, and add and save your own changes without uploading them. This is useful if you want to add or manipulate special items in the file, and then generate a custom Garmin map. Cheers.

It looks like you needed to join the individual lines of the lake into a single polygon. If the whole lake isn't one single way, it can't be rendered properly. It seems that someone fixed this, just as I was looking at it. Try reloading the map tomorrow, to see if the lake is there. You should be able to log on to the forum with your existing OSM user name and password. See the information here: http://wiki.openstreetmap.org/wiki/Forum Cheers

It normally takes a day or so for your edits to turn up. Try again tomorrow. I noticed that if I turn on the Osmarenderer base layer, a large body of water does turn up: this also generally means that you have to wait for your edits to be rendered. Although OSM may be of interest to Geocachers, I would really suggest that you post such questions in OSM's own forums: http://forum.openstreetmap.org/ Cheers

If you have tried this on several computers with several cables, then you may as well restore your unit to factory settings. If this doesn't work, you may have a defective unit: you should then contact Garmin support. By the way, reformatting the SD card may only help you temporarily: you need to remove the hidden files which Mac OS writes to the card. If you do not do this, and are unable to update the firmware, the shutdown problem may reoccur. Cheers.

This symptoms you describe are similar to those caused by the Garmin unit reacting badly to the hidden files which Mac OS writes onto the SD card. Garmin fixed this with a firmware update: this is the first thing you should try, if possible. Search the forum for further information on this. Cheers

Check out the Open Street Map wiki. Here's the Beginner's Guide: http://wiki.openstreetmap.org/wiki/Beginners%27_Guide Since you mentioned mountain bike trails, take a look at Openmtbmap.org to get an idea of what is possible with Open Street Map data. Openmtbmap.org produces specialized routable mountain bike maps based on Open Street Map data: http://openmtbmap.org/ Sadly, for the moment, Openmtbmap.org has maps for just about everywhere, except North America, so this will be of limited use for you. It does demonstrate one important concept of Open Street Map though: the data you upload from your tracks is saved in the database in a completely independent format. The data can be then converted into all kinds of other things, such as online maps, special hiking or biking maps, etc. The Garmin-compatible maps produced from this data are just side-projects. (This is perhaps why you could not find your hiking trails in the maps at http://garmin.na1400.info/routable.php. The maps there either do not include hiking trails, or they were updated before the hiking trails were added.) At any rate, please do add your trails to the Open Street Map database. We can then all benefit from them. (Plus mapping is almost as addictive as Geocaching.)

If you download the gmapi files, you first need to install them on your Mac. Double-clicking the file should be enough to start the process (this should start Garmin's Map Manager program, which will install the map for you). The map will then show up in Garmin's Roadtrip program, if you have installed the map correctly. And finally, to copy the maps to your GPS unit, start Garmin's Map Install program, select the maps you want and transfer them to your GPS unit. I don't know why Garmin decided to create three different programs for managing maps. I suppose it makes sense in some way. If you don't want to go through all that (it's actually not as difficult as it seems), you may be better off downloading the img files which you can copy directly to your GPS unit. Hope this helps.
