Magellan Sportrak Pro. It's been nearly a year since I've used this. A blown knee took a lot out of the season.
Anyway, for those of you who have it, here are the update instructions. It is pretty arcane and not very clear on the Magellan site what you need to do, but presuming you have an old one, here are the steps to get up to date:
"Firmware Update":http://www.magellangps.com/en/support/software.asp. Go to the Magellan Firmware updater and get the latest MAGUP file. The current version is 5.4 and you have to download. Because the Sportrak Pro has limited memory, you have a somewhat painful choice. Load the "Standard" version and you get turn-by-turn directions like a car navigation system or you can use the "Marine" version and then you get tides and currents. You can't have both, so you basically decide and then reburn the unit.
Firmware Installation is also a little confusing, but the readme documents it. You must follow instructions exactly to avoid corrupting your unit's flash memory.
"Mapsend DirectRoute NA":http://www.magellangps.com/en/products/product.asp?PRODID=950. Version 1.0 was called DirectRoute, but version 2.0 is called DirectRoute NA since they also have one for Europe and other countries now. This is the equivalent of a car-based navigation system. It has turn-by-turn instructions. I have version 1.0a and had to upgrade to 1.02 because of an XP SP2 bug (see below). The most recent version is v2.0 that is just coming up. It is $99 if you want to upgrade. Install the software that you have. With Windows XP SP2, there is a bug, so you need "1.02":http://www.magellangps.com/en/support/products/msupdate.asp of the application to get around a problem. "Mapsend Topo 3D":http://www.magellangps.com/en/products/product.asp?PRODID=1044. I I have the older Mapsend Topo that is now obsolete. They have a new program that has streets and also a 3-D view as well called Mapsend Topo 3-D. This is good for those of us who are hiking. Cost if$150 list for the newer one. I hate this upgrade business. It might be cheaper just to get a new GPS rather than pay for the software. "Tigergps.com":http://www.tigergps.com/magsporproha.html has this for $80 "Mapsend Bluenav":http://www.magellangps.com/en/products/product.asp?PRODID=181. These are the navigation charts for marine use. This is a little strange in that you can only "checkout one" chart at a time but they are all locked there. If you are using this a bit, then you do need a new GPS that uses SD card to store the things. "PC Data Cable and Cigarette Lighter Adapter":http://www.magellangps.com/en/products/product.asp?PRODID=127. These GPS systems suck down AA batteries like there is no tomorrow. So in a car or a boat, you pretty much have to have a cigarette lighter adapter. There are two versions. The$44 one includes a PC Data cable so you can sync a laptop on the road. There is a $23 "Power only":http://www.magellangps.com/en/products/product.asp?PRODID=124 as well that is great for those times you don't need a laptop connection. It is "$14":http://www.tigergps.com/magpcexpowca.html from TigerGPS.com
