This is a description of how I use GPS. It's a collection of the stuff I use, and which has proven usable.

I built myself a nice little setup made of inexpensive parts that gives me moving maps on a rather large display of a handheld together with the ability to use my gps alone (e.g. when it is very wet out there...). Here's what I use:
Lots of pages out there about this yellow little thing. No need to say more, suits my needs perfectly. But be careful with water...
A first generation WindowsCE powered (at least this is written on the case, I'm still searching for the "power" of WindowsCE...) handheld. Not sold in stores any more, but should be available cheaply at ebay or something. One of the finest pices of software I have ever seen. No important bugs so far, incredible speed even on my old Cassiopeia, handles HUGE (talking about 700MB) maps because of its clever proprietary map format.
Version 1.10.7 runs fine now, even with sound announcement. I cut a Casio E-10 Serial Cable Adapter in two pieces, connected the open end with a cheap Garmin plug and WOW there it was: my personal "E-10 to eTrex" cable. Works perfectly.
At first I started scanning maps. It's difficult to keep the maps straight while putting them on the scanner, otherwise your pieces will not fit together. I used photoshop to distort the scanned pieces so they a straight, but this is not working too good. You can use rasters printed on the maps to see if the scan is sheared or rotated and try to fix it.
Now what I think is much better is using maps from the net where available. Fortunately the german (bavarian) and austrian governments offer high resolution topo-maps which you can download in pieces and put together, and for road trips map from the net (Expedia, MapBlast, MapQuest) are much easier to use, and mostly precise enough.
After Mapblast stopped using coordinates in the url we all need a new possiblity to get our coordinates. For those of you where G7ToCE does not work for uploading waypoints from a CE device to a Garmin GPS here's another solution, a little ugly, but it works. I formatted it so that you can read it well on a PalmSize PC. How to convert OziCE waypoints to Contact me at: Disclaimer:

50.108N8.667E 's Setup
eTrex
Casio Cassiopeia E-10G
Really quite an old one, but tough (got it stripped onto my bike for many kilometres now, still works fine) and still fast enough for GPS. OziExplorerCE runs fine on it, not at satellite-moving-speed, but fast enough to be really usable.
Biggest backdrop is you better have spare rechargable batteries with you all the time and can't use it at night (runs approx. 5 hours without backlight, about 30s with backlight on ;-)
OziExplorerCE Moving Map Software
You simply load a map from the net, use the demo-version of the PC-OziExplorer to calibrate it, put it on the WindowsCE-device and off you go.

Cassiopeia - eTrex Datacable
When conneting a handheld with a Garmin directly remember you have to cross the two data wires of the serial cable, because they both expect a pc's serial port...which is of course not there, because you connect them directly. So by connecting the "Transmit Data"-wire (TxD) of the garmin with the "Receive-Data"-wire (RxD) of the handheld and vice-versa you simulate for both of them to be connected to a pc...right?
50.108N8.667E 's Map Tips and Tricks
Expedia-Maps
I found a good way to treat Expedia maps that suit my needs to calibrate the maps later. It needs a little handwork to get the map you need, but it works.
Expedia maps can be max. 2000x2000 pixels wide and include as many "pins" as you need. Pins can be used to have exact points on the map to use for calibrating.
To find the coordinates go to www.maporama.com and search a city near the coordinate you want to find. Then copy the coordinate (after the "c=") from the image url and paste it into the pin-part of the URL I wrote down below this paragraph. Copy and paste this URL into your browser and modify the pin-coordiate until the pin is athe point you want to get. Then you know its coordinates! Here is the syntax for an exmample map, it shows an overview map of Hesse
____ CenP=center coordinate
| _____Alti=map-detail(=scale)
| | p=pins___
| | s=size(pixels)_______ |

Converting OziCE waypoints to GarmapCE waypoints
You have to install GarmapCE, a free moving map program that is too buggy to use it for moving map navigation, but works fine for uploading waypoints to the garmin. The problem is that OziCE and GarmapCE use different formats for their waypoint-files. So we have to convert them, which is a little complicated on a CE-Device...as you see.
GarmapCE waypoints:
- Save Ozi WPs as "ozi.csv"
- Open "ozi.csv" in notetaker
- Delete first 4 lines
- Replace , with ; and save
- Open in SpreadCE
- Delete all columns except
WP-Name,Lat,Lon,WP-Descr.,SymbolNum
That means: delete cols A,E-J,L-T
But take care, colum names change
while deleting, so actually delete
A, then D-I, then E-M
- Save as "ozi2"
Type "Comma Separated Values"
- Open "ozi2" in notetaker
- Replace ; with , and save
- Import into GarmapCE
