Well I tried the fizzycalc program but while it was easy to use I question the result.
I used to points that I collected which I am guessing are about 450 ft apart yet the result came back 4965,713 ft?? The forward azimuth was 78 degrees which could be correct??
These are my points N35 09.403 W106 29.187
N035 09.565 W106 28.210
Those two coordinates are about 0.9 miles apart, also known as 4965.713 ft (that's POINT 713 feet) and the bearing of 78 degrees from #1 to #2 is correct.
Note the decimal, not the comma. Something in your story (website or program or the computer you were using) is set to European/S.American or some similar regional setting (see Control Panel in Windoze) where they use a comma instead of a decimal to denote the decimal portion of a number. (And vice versa - a period is used to seperate numbers over one thousand 65.535 is 65 thousand five hundred and thirty five)

Just highlight the track or the whole GPS Sensor entry in the left hand 'Places' box, then Delete

I use my c330 as a 'coarse' caching tool all the time, it does make life easy.
You can use MapSource normally with the c330. (The 330 even works with nRoute normally too if you want some redundancy)
The only thing I dislike is the point by point method you have to use to delete uneeded wpts (or you can do a reset but then have to reset all your preferences)

Unless your radio is expecting it, it'll be a lot of work.
Here's an example: http://www.icomcanada.com/products/marine/m504/m504.htm
Of course, some FRS portable radios have GPS built in.

Isn't there a GeoCaching setup where you have to tell it what icons mean to find/found?
Maybe they got reset.

330c Reset: Hold down the lower-right corner of the screen on power-up.

I concur.
Though we did do 10 caches today with the help of my 330. I had uploaded all of them to the 330 with the PC and used the 330 to get us to the area, then the 76CS to finish them off. The 330 really made driving to the caches nice.
Another annoyance is you can't delete a group of waypoints (like found GCs) at once, only one at a time with about 5-6 strokes needed for each. That was a major bummer when I accidentally uploaded about 100 unwanted wpts.

You can usually look at the full, native, unmodified string by running HyperTerm or similar serial communications program. Every second or 2, a new set of NMEA strings will scroll up the screen. NMEA is always ASCII text, so you'll be able to read and understand them easily.
After a few sets go by, turn off or unplug the GPS and you'll be able to study the strings (or capture a few to a text file). Some will show time & date, others position, others movement, other routing, others give information as to your destination, etc..
You just have to make sure your GPS is in NMEA mode and your terminal program is set to the same baud rate & serial format (4800-N-8-1 usually) as your GPS. Your owners manual should show the serial spec in the back somewhere.
-
Also check the datum of your unit (GC uses WGS84 but some placers throw in a different datum to make sure we're awake, especially calculated cache locations on multis).
A datum difference can show up in many forms, in some places the same position, in others a straight or diagonal shift.

I had an interesting observation a couple weeks back. A group of us were hiking up a fairly deep, narrow canyon. My 76CS didn't get a lock. My buddies 76CSx got a lock, but looking at the data after in MapSource, in most places his was obviously out to lunch by 70+ meters.
I'm thinking his greater sensitivity was picking up signals after they bounced down off the rock walls (multipath) a couple times. So the greater sensitivity in this situation didn't really get him anything. (But of course in other situations it would)
-
A buddy of mine just got a Garmin GPSMAP 296 and is *very* impressed as it has a full Jeppesen database plus you can load in Metroguide, topo, etc. Has voice prompts, routing, etc..
-
I do remember something about this, though it wasn't 2000, it was the GPS clock rolling over after 1024 weeks or something.
Anyways, www.garmin.com has firmware for old units still on their site, push in the new firmware and it should work.
Hmmm, I just looked, there isn't anything for the 40 or 45 (though the 48 is up to v4.60), I'd suggest contacting them.

Saving the active log into a saved track also deletes the altitude info if I'm not mistaken?
You can edit the tracks after you download them, copy it, rename it, then paste it (takes over original name). Create as many seperate tracks as you have sections you wish to keep seperate, then go into each and highlight/delete points outside the area you wish to map. It's pretty easy to see the breaks as the leg distance is quite a bit larger than normal.
But also, doesn't the new beta MapSource products let you split up tracks, etc? I haven't played with it much.
It's late
so I hope I'm not too out to lunch here, I should be asleep -

Just so no n00bs get confused, I just wanted to point out that MapSEND (Magellan) and MapSOURCE (Garmin) are two different products by different manufacturers. They use different maps and very different executables and don't load into each others GPS units.
-
Something along the lines of this might work.....
Control Panel/System/Hardware/DeviceManager/Ports (COM & LPT)/Communications Port (Com 18) and Double click on it.
Port Settings tab may have the ability to apply a new port #?
-
The base maps are *very* basic, they're a guideline at best.
The extra mapping products are a different story.
-
Virtually any computer store / Staples/Business Depot/Office Depot/etc will sell them. Belken is a common brand & mines been flawless for 3 years.
BUT: follow the install/config instructions exactly to save potential headaches.
-
The older versions of MapSource (6.5 and lower) do it, the newer versions do not, you have to download nRoute as someone mentioned.
It doesn't really matter which maps you have installed, in fact you can have no map, it is just the MapSource program that does the recording.
-
Streets & Trips works fine, you just need the serial connection (not USB) and set the output format to NMEA (not Garmin).
Assuming it is a laptop you're using, you need a serial port (or USB->Serial adaptor installed & properly configured to be COM 1..4).
In S&T, Tools/GPS/Track.
By S&T won't record anything onto the PC, just show your position.
There are some workarounds, (turn you trcklog into a series of S&T waypoints for example)
Maybe something has changed in the last year on this front?

-
To get out of NMEA and into Garmin mode, goto Main menu / Setup / Interface (at least that was on my old Vista not-C, should be at leatst similar on your C.

Nevermind....

There are probably other ways, but how I did it was to use MapSource (Garmin's PC program) and made two waypoints with your two coordinates, then just used the Distance/Bearing tool and set my start as Point #1 and moused over to point#2. The distance & bearing shows up in the status line at bottom.
Make sure whatever program you are using is set to True North for bearing and to Degrees/Decimal Minutes to use your coordinates in the format shown (or convert your coordsinates).
