I a very long time user of Garmin GPS's, currently have GPSMAP-60CSx, several etrex units a gps-12, nuvi 750 and 3-nuvi 255w's. I got the 255w units for my kids and thought I'd do some tinkering with them before I turn them over. I have some basic questions about these units and found this neat site doing a search. I've converted several hundred ver3 *.gdb files to *.gpx files, used sub-folders to separate the different groups and place them in one folder to use with the POI Loader.
1. Never used the *.csv file ext/format before. What are the biggest differences between it and the *.gpx format?
2. Has anyone figured out how to make the CN 2010.4 map set show up on NRoute? I know the Nuvi will not work as a receiver, guess Garmin didn't mean for it to be.
3.Can Map Icons, or anything be made to show up other than the default "Dot" that shows up on maps (without saving the POI to Favorites then editing icon)?
4.When using a 4gb SDisk loaded with topo usa 2008 (or any other Map set), what happens when the Nuvi has both the CN 2010 and Topo map sets selected? I suspect the City Nav will override the Topo and you'll have to switch between the 2 map sets. OR, will they both show up, allowing an autoroute to occur, while seeing topo info?
Calling Garmin has become a big hassle as well as a very long wait time, especially when trying to get to the right people, you'll be put on hold a min of 2 times. I appreciate any help. If I can help you guys with any questions on outdoor units such as I've listed, or the use of NRoute or Mapsource let me know. Thanks
I'll try to answer some of your questions. Others will tackle them too.
In a word, readability. CSV files are easily read and understood by humans. The other advantage is they are easy to create and edit. Working with GPX requires some advanced knowledge and a good editor to manipulate the data.
Custom icons can be created and displayed for your custom POI. The POI-Factory has a good selection of icons for the various files. Custom icons do not replace the factory supplied icons. You can also load custom alert tones as well. The 2XX and 1XXX units without an MP3 player require WAV files and a converter program called SOX. Look through both the FAQs and on Gary Hayman's Tips, Tricks, and other essential items for instructions on using custom icons and WAV sounds. http://home.comcast.net/~ghayman3/garmin.gps/index.html
I personally have no experience with the Garmin TOPO maps but I know the CN overrides others such as those loaded from GPSfiledepot.
Sometimes you just have to bite the bullet.
Anyway, welcome to the site. It is addictive as "Boys (and girls) with their toys..."
