With the palm version of GMXT I still get an alert (some beeps) instead of my custom sound for proximity waypoints. The same for a tourguide point, instead of the audio portion it just beeps.

My guess is that one unit got a lock on #10 when you were at a different location and when you were looking at both you were in an unfavorable location so the second unit was having problems locking on to it, the other unit already had a lock on it and was able to maintain it.

Clearly a case of "One test is worth One-thousand expert opinions!!!" This points to the fact that to date, people have been talking to tech reps, translation salesmen. No one has been talking to factory engineers who actually designed the Colorado. Lots of devices can use the bottom 2GB of an hd card - its that top 2GB that may or may not work - I stick with the tech notes that say hd cards shouldn't be used. That's not what I've heard. From wiki: SD and SDHC compatibility issues As of early 2007, the simultaneous availability of non-standard 4 GB SD and 4 GB SDHC cards, and incompatibilities between SD and SDHC have caused confusion among consumers buying memory devices. SD and SDHC cards and devices have these compatibility issues : * Devices that do not specifically support SDHC do not recognize SDHC memory cards.

I tested a 400t at REI today and it was able to read my 4GB SDHC card (I was able to display pictures from the 400t's picture viewer that I had stored on the card). So it seems that SDHC is not a problem, and if it can use a 4GB SDHC card chances are that it can use bigger cards as well.

I'll see if I can turn off the maps and then reboot to see. It does say "Loading Maps..." for quite a while during start up. --Marky Probably because the map contains over 6000 segments. Another reason to come out with a topo map with a reasonable number of segments.

It appears that the City Navigator NT1 maps will have DEM info embedded in them so if you want 3d street maps you'll want to wait until those maps become available.

The format of the NT type maps require that the routing data is always sent. For non NT maps you can choose to send it or not.

I doubt that you can change the id of an SD card. When you buy a card with preloaded maps that are locked, there are two files on the card. One file is gmapsupp.img which contains all the maps, and gmapsupp.unl which contains the unlock code which is based on the pid & fid of the map and the id of the card. If you have a gps with preloaded maps such as a nuvi, the same applies except the files are gmapprom.img and gmapprom.unl. You can use a program called gmaptool to extract the individual .img files from the gmapsupp.img or gmapprom.img file so that you can use MapSource with the map. The maps are still locked so you can't load them to another gps without entering a proper unlock key into mapsource. So you can use MapSource to plan a route. If you have a gps with preloaded maps you can contact Garmin and get the maps on DVD to use on the computer. However this can depend on the rep you talk to, most will send you the DVD for free, some may want to charge a small fee (around $15), and some may even say you can't get the DVD at all. So depending on the answer you get you may want to just call back. Getting the DVD is preferred over dissecting the gmapprom.img file since it is easier and by dissecting the gmapprom.img file you can't reconstruct the _mdr.img file which means that you'll lose the ability to search for addresses.

It should give a 3d view for any map that has DEM info, that would include US Topo 2008, Topo 24k national parks v3 (v2 doesn't have DEM info), and a few 3rd party European maps.

Nice guide. I haven't done a formal test, but the nuvi 760 seems to give an alert for proximity points even when not on the same road as the point. It will also crash if you turn it on and you are within the proximity of a tourguide point.

Thank you - I've been trying to get this to work with Garmin Mobile XT but not having much luck. Maybe something that it just can't handle yet, but your "cookbook" will help me find out! GMXT, at least the palm version doesn't support custom sound for custom POI's. It also doesn't support pictures linked to custom POI's.

Correct. Currently the program won't work with the Topo 2008 maps, I have to modifiy it to work. I'll post here when I have a new version.

300 versus 400t: When I select all of US Topo 2008 in MapSource instead of getting the number of maps and the size I get the message "The map set is larger than 4GB" in red. Since my largest SD card is 4GB I can't test to see if it will generate the map or not. So it might not be possible to load all of US Topo 2008 onto an SD card to use with the 300. Something to consider...

gmaptool won't solve the problem. The problem isn't that you can't create a mapset with more than 2025 map segments, it's that the 60CSx won't be able to use more than the first 2025 segments in the mapset.

There will be no performance related issues.

Hi Anders, It looks like from the gpsmagazine review that they eliminated the POI categories such as "Food & Drink", "Lodging", "Attractions", etc. and just lump them all together, is that true? Rich

I don't know if the 60CSx can handle cards larger than 2GB or not, but even if it can there is a 2GB limit on the file size for the FAT32 file system. I was wrong, there isn't a 2GB file limit for FAT32. I was able to create a 2.5GB mapset on a 4GB SDHC card and use it in a Nuvi 760.

I don't know if the 60CSx can handle cards larger than 2GB or not, but even if it can there is a 2GB limit on the file size for the FAT32 file system.

Not a handheld unit, but there is this: https://buy.garmin.com/shop/shop.do?cID=134&pID=10573

1) Some Garmin units have an option to display urban areas or not. I don't know if the HCx has that option or not, if so it could be turned off. 2) If you use a .typ file with your maps you can change how points, polylines, and polygons appear for the map. So you could use feature point type 0x6417 (manmade place, other) for the railroad station, and customzie the icon that's displayed for that type with a .typ file). 3) There aren't any transparent polygons in the traditional sense, best way would be to use polylines to make a grid, again you could use a .typ file to control how the lines look, you could make them a very light grey so they don't stick out too much.

For non-NT versions of City Navigator you have the choice of sending routing data or not, for the NT versions you don't have a choice, routing data is always sent.

I assume you are talking about the topo maps since there shouldn't be any issue about loading all of City Navigator maps: http://forums.Groundspeak.com/GC/index.php...=170615&hl=

If no one sends you the file, let me know and I'll walk you through the process of generating a new one.

I did a search from the United States Patent and Trademark Office website and don't see where they have registered a trademark for "GeoCalc", just "The Geographic Calculator".

I want a streetpilot 2xxx in the nuvi widescreen form factor with high sensitivity chipset!!!
