How do I create a route with waypoints or POI's using Google Earth for my Garmin c340?

I don't believe routing is available in the c3xx, c5xx or Nuvi models. What you can do is load your waypoints into a single POI on your GPSr and as you travel, change the GoTo to the next POI you want to travel to. The locations will always be listed in order of their distance from your current location.
I believe an offshoot of this process would be to set up the trip as a GoTo to the final destination, and then periodically add your closest POI (as above) as a midpoint. You do this by selecting GoTo after a destination has been added, and selecting the new midpoint. It will be added to the route, but you can only have one. I haven't tried it, but expect that once you pass that midpoint, you can now repeat the procedure with the next POI until you reach your final destination.

I appreciate the quick response. I kind of figured that is what I would have to do. I set up a test last night and tried it on my way to work this morning and thats exactly what I had to do.
Again, appreciate the help.

That's seem to be a very good idea.. I was wandering how to plan a trip from the computer rather than from the gps itself. I really like this idea and will try it.

Thanks.

I just received my first GPS today (nuvi 350). I find this to be very limiting (the lack of multiple way points). However, after some searches, etc. I'm wondering if you could create a tourguide (gpi) without the audio portion to make this work? It could also be that I have no idea how tourguides work.

Garmin TourGuide POIs are currently compatible with the nüvi™, zūmo™, and the StreetPilot® c550, 2730, 2820, 7200 and 7500.

You can setup a list of waypoints as a custom POI, at least in Garmin.

This can be created in Excel or notepad and needs to be saved as a .csv file.

The first 2 columns need to be the geographical coordinates (first longtitude with a - sign in front and in th esecond column latitude (no minus sign) and the 3rd column the name of the stop and the 4th column the address

Name the file after your trip, for example California Coast.csv

Please note thatfinding these coodinates can be hard, but if you have a copy of MS Street and Trips you will find under the Tools menu an item called Location Sensor which when started will display the coordinates.
I found MS Streets and Trips a nice complement to the GPS, though I am still new to GPS.

Once the file is created it and saved to your Custom POI folder then you can add the trip to your unit.
It would be nice, at least in Garmin to add new POI's one at a time without restarting each time.

Good Luck

There is a site that can convert address to/from latitude/longitude. Better yet, it can convert batch mode which I find to be helpful. I am planning a trip to L.A. and have create a Excel csv file contain a Custome POI foler as you had mentioned. Help this can help others..

If you want to find an address coordinates, GPS Visualizer is a great place to start.

Thanks Guys,

Neat sites, but if you get a chance to see how Microsoft Streets and Trip does it, you will be thrilled. I have version 2007.
You don't have to type anything ... just point.
It lacks the batch functionality mentioned.

On most of the newer Garmin models meant for automobile use they allow only one waypoint. That is a shame. Most of the time you don't need 20 waypoints but if they would have given us 3 waypoints on a given route that would have been a big help.
