"Custom map' is confusing. It had been used for years by indepenent map authors producing more detailed maps than Garmin offered. Garmin recently started using the term for imagery, of the land's surface or paper maps, which one could view on the CO, OR & DK units. The vector mapsets will work fine on your GPSr.

I and others have noted an error message above 96 'cells'. I have never noticed where the missing data is when using a single .kmz file with 100 cells.

The buttons on the top of the screen allow for one handed operation. Unit is stable in the palm of the hand and is also held by four fingers. Thumb operates buttons and does not block display. The 76 has a MOB (man overboard) button and works wery nicely.

Most maps on gpsfiledepot are self-installing .exe files. On a PC you need to run the file. Then in MapSource the smallish rectangular box near the upper left corner will list which mapsets area available. Also see: http://www.gpsfiledepot.com/tutorials/how-...armin-gps-unit/

On my OR300, it is a CustomMaps folder within the Garmin folder. It have not updated software/firmware to use Birdseye imagery, so Garmin might have changed this. FYI - custom imagery was limited to a total of 100 (error message if more than 96) cells of no more than 1024x1024 pixels each. Using a different extension, you can have more in memory, but you need to have some way to access the GPSr and change which files are active by changing extensions.

If you changed location by a considerable distance, which you probably did going to Taiwan, the GPSr needs to reacquire almanac data from the satelites. This could take 30-60 minutes. On the older units you could speed this up by giving your approximate location - just checked on my OR300, but did not find a way to do that on it. Also noticed two of the strength bars were green border with white fill which I do not recall seeing before. BTW, when you return you will have to reacquire the almanac.

Anyone know if the 100/96cell limit for 'custom raster imagery' has been increased?

62L01 used to refer to a 1:50,000 scale map. Has something changed? I thought this was the source data Ibycus used for his Canada Topo mapset.

On printed maps the contour interval used is determined by the scale of the map and the relief of the area. This is also true on GPSr maps and is also effected by the scale and type of available source data, the zoom levels the map author uses and the intended purpose of a mapset.

Garmin's CN and 24k topo products are routable; most other mapsets are not.

That seams to imply that the 24k product also uses Navtech data for streets and roads; which I had not heard before.

You mignt want to check http://www.gpsfiledepot.com/maps/view/250/ This is an overlay/transparent mapset of the trails on the USGS 100k quads - which may be the source of the trails in Garmin's 100k product, or it may not be.

Nothing like putting out a inadequately check-out defective product before your going to be closed.

Also try: setup / map / advanced setup / zoom levels / street label / - may have been turned off or set to some zoom level. You may also have switched to some dashboard which has them set to be off, etc.

Does BaseCamp obtain a position from the GPSr? There was a question a few days ago about displaying the image on the GPSr on a laptop and also showing the current location. In looking into it, I was surprised that MapSource obviously would show the data that was in the gmapsupp.img file sent to the GPSr but could not receive the current location from the GPSr to display on the computer screen. Other programs I had available could either display the .img file or plot the GPSrs location on some other format of map, but not both.

On the page with the listing of all the individual quads, press menu, this should bring up a page listing the individual maps. This allows you to hide/unhide all the quads in a mapset at one time.

Keep an eye out for posts on sales and google prices. The past few months is seams like every few weeks one of the outdoor/camera/electonics stores has had a 'super' deal on a unit.

You might consider one ot the ORxxxt units. A few days ago there was a post (on gpsfiledepot ??) about a 't' unit for $5 more than the non 't' unit. The 't' unit had the topo mapset taking up 3Gb of the units 4Gb of internal memory (my OR300 only has 1Gb of built in memory). I believe you can still put a 4Gb storage card into the unit. If you removed the topo mapset (saved to hard drive or write a DVD), this would give you close to 8Gb for you own data. What would likely limit filling it up would be finding mapsets which were created with .img files averaging 2Mb. The CO, OR, DK units have a 4000+ segment limit. These units also allow you to rename the gmapsupp.img file to anyname.img (i.e. NMtopo.img, COtopo.img, etc.). Once you had files built for the individual states, you could transfer them to the GPSr as you needed them within the 4000 segment/ 8Gb memory limits. The mapset file sizes on gpsfiledepot are for the .exe file. When the .img files for the mapsets are 'unpacked', the mapset may be up to 20% larger.

24Mb internal should be OK for a 30 mi radius. How much room a topo needs depends on the level of detail, how large an area the map author used for the quads/tiles, and how 'complex' the topography is. Check the mapset as some Garmin products use very large quad/tile/segment sizes which would be too large for a unit withoud the card memory.

Anyone have a feel for the usual sequense of contour intervals use on non-US metric maps? Scale would likely be around 100k to 150k Which of the following might be best (larger value where steep slopes, smaller in flat areas as appropriate)? 60 - 30 - 15 - 6.5 ?? meters 50 - 25 - 12.5 ?? meters 40 - 20 - 10 - 5 ? meters

If you mean water depths; there is not much of that info available. Keep your fingures crossed. If you mean land topo around the lake; see gpsfiledepot.

Not sure you would have these on a 60. On my 76 I can 'pan to coast, / find / marine points / tide station / select one from the list'. Tide stations for the US is built-in; Garmin did have a file on there website which included tide stations for some or all of Canada.

Ahh, now I see. 'The Republic of Elbonia is a fictional country supposedly in the Balkans from Scott Adams' comic strips Dilbert and Plop: The Hairless Elbonian' You a really staying home and taking a virtual trip. Both cloudmade and mapcenter2 have maps for Romania.

3/24 is about 14%. Are you physically located in the area or did you pan to the area transfered to the GPSr? Did you zoom-in enough (as 800') for the data to display? Which mapset?

Is the sometimes shows related to zooming with both mapsets enabled? I have seen this when the 'display levels' are not the same in both mapsets, but I would expect Garmin to use the same levels.
