It is common knowledge that you can't load tracks onto a Nuvi. That is not true. I have tried a couple different GPS options and I am pretty happy with the Nuvi for ADV style riding for a couple reasons. Mainly because it is cheap, $20 will buy a Nuvi off of Craigslist. On longer trips I carry a spare unit in case I smash one off of a tree or it gets stolen. Many people suggest using a phone but I found the downside of that, if it falls off the bike and disappears in an area of no cell service, the phone is gone and you are out $700 for a new one (ask me how I know about that. :/ ). Then you have no communication method once back in cell range. If you rarely venture down a bumpy road or ride in foul weather, a phone might be ok. How to use a Nuvi: 1: Buy any Nuvi that has a memory card slot (most, if not all have that). $20-30 will buy a GPS from Craigslist. 2: Create or download a GPX track (not a route), a track is like a highlighted route on the map, you can not interact with it. You ride and keep your icon on the track, if you stray from the track, it does not route you back. If I stray too far from the track, I drop a pin on the track where I want to return to it and let the GPS route me back. Dropping a pin and doing different routing will not effect the track that was already loaded. I am getting ahead of myself here. 3: Now the GPX file is on your computer, what to do with it? Install "Image from GPX" on the computer. http://www.javawa.nl/imgfromgpx_en.html Use that program to make the GPX into a file named GMAPSUPP.IMG (a separate box needs to be checked on the screen). 4: Next take a memory card and create a folder named Garmin on it. Put the GMAPSUPP.IMG file in that folder. 5: Insert the memory card in the GPS and follow the line. You can experiment with different line colors that work best for you, I prefer lime green. Different colors disappear at different zoom levels on the Nuvi. Green seems to stick around the longest. Weatherproofing the Nuvi: clear silicone caulking is mandatory around the edges of the screen and in the ports on the front. Use tape to keep from getting excess on the screen. The memory card slot does not need to be sealed unless it is going to rain real hard. Water will get in and interrupt the connection between the memory card and the GPS. Taking the card out and drying it off will fix that. Some duct tape over the slot will make it waterproof enough. One downside is points of interest are difficult to mark in a track. Maybe someone has a different solution but I actually draw a small circle track around the point of interest and label that track as to what that is. Like a gas station. My Nuvis are not real reliable in knowing where every gas station is located. I use my phone for that and then input the address in the Nuvi. I would like to credit the folks from this thread a year ago when I first started exparmenting with the Nuvi. http://advrider.com/index.php?threa...-tracks-on-a-nuvi-1350.1112949/#post-28286454 I wanted to create a more generic Nuvi thread that would be easier for people to search for. Since that time, I have done several long trips, including a 2000 mile ride where it rained almost the whole time. I also did a 4000 mile ride with the wife (who has the same setup as myself) that was largely off road and very dusty.
