Zumo 665 problem

[JohnG]

This weekend I tried to jump into the middle of a custom route when riding with my Garmin Zumo 665. I was already on the route, so didn't need guidance to it; just needed to start navigating the route from where I was. I had recalculate "off".

After I selected the route from the Custom Routes list, it asked me if I wanted guidance to the start of the route. I replied no. Then it took a moment and said that it didn't have enough memory to calculate the route.

Has anyone else seen this? Do you know what caused it? Is there some way to start navigation in the middle of a custom route?

Thanks, John

How many custom routes do you have stored on the gps? Mine did the same thing until I cleared some of my old custom routes.

Kevin may have hit it on the head. Typically, I only keep routes in the GPS that are to be ridden that day. On the way to STAR, I kept 4-5 days worth of routes but deleted that day's route each night. I've never had trouble with my GPS when I ask it to start
partway in a saved route.

Good practice. On the 660/665 you can load as many routes/tracks as you like on the "garmin" drive in the GPX folder. Then only IMPORT the ones you want to use today after deleting all the old ones.

Thanks for the replies.

Kevin, I had eight routes stored.

I just did some experimenting. Here are the results. I have a memory card in my 665 in addition to its internal memory. I am running BaseCamp with Windows 7 on my PC.

On BaseCamp, there are two folders visible under zumo 665: "All Data" (internal memory), and "Memory Card". I "sent" (using BaseCamp) one route to the All Data folder and another route to the Memory Card folder.

When viewed from Windows 7, I see a "Garmin zumo" drive and another removable drive for the memory card. On the Garmin drive I see a GPX folder (among others) that has a "Current.gpx" file and a "temp.gpx" file. The GPX folder also contains an "Archive" folder which in turn contains five ".gpx" files from several days to several months old, each of which is larger than the ".gpx" files in the GPX folder.

On the memory card removable drive I see a "Garmin" folder that contains only a "GPX" folder. The GPX folder contains the route, track, and waypoint GPX folders that I just sent to it.

When I "eject" the zumo from BaseCamp, the 665 begins normal operations and asks me if I want to recalculate a new route for its internal map. After I reply "yes" it works for a while and then has available the custom route that I imported to the 665 internal memory. At this point, the route that I imported to the memory card is not visible on the 665.

After I disconnect the 665 from the PC, then turn the 665 off and back on, it tells me that it has a new route (the one on the memory card), and asks me if I want to import it. After I reply "yes" it works for a while, and the new custom route is available on the 665. It appears that it has been added to the Garmin/Current.gpx file in internal 665 memory.

From all of this, it looks like what I probably need to do is "send" routes from BaseCamp to the memory card and keep them there until I plan to use them, then import them to the 665 internal memory. That will minimize the internal memory use.

The only question I still have after all of this is what is the Garmin/GPX/Archive folders and what are the large .gpx files that it contains? They don't seem to be visible or manageable via either the 665 or BaseCamp. Can I just delete them from Windows? They take up more space than the files that I am actually using.

Thanks for the help.

Best, John

Just guessing that the large .gpx file is stored tracks. On another Garmen model, erasing or replacing this file had no long term effect. It was restored by the OS when the GPS rebooted.

Most reliable workflow:
1. Work only with the Garmin\GPX folder on the Garmin "drive."
2. Delete all files in this folder or move them to the archive folder.
3. Copy new GPX files that contain the routes/tracks/waypoints you are interested in to that folder.
4. eject & let 660 reboot.

This workflow makes it faster/easier for the 660/665 to "find" new files. It makes for less confusion in finding what you want to import. My experience is that putting GPX files elsewhere, it takes longer for them to be found and they may not be found at all. Use the removable memory card for additional mapsets, mp3 anf jpeg files.

I'm unclear just what you guys are talking about. I have had my Zumo 665 for several years now and seem to be able to do most anything with it. I keep very little on the "active" memory side and ALL the data on the card. Music, photos and everything else is pulled off the Data card as needed.
I "store" all my old routes as well as routes I intend to use on the Data card. I only import one at a time. With a 16 GIG card, (regardless of what the book says, it works just fine!) I can store a seemingly unlimited amount of routes. Worth noting, I delete the current route (he one I just used) from the "active memory" when importing a new route. Even deleting the active route, it is still there should I need it on the data card. Just one at a time so the machine doesn't have to use up too much resident memory.
FYI. I have gotten comfortable enough to simply "built" my routing on the machine itself. No recalculating or importing is necessary. It built the route with the maps it currently is using. I also NEVER let it "auto recalculate". Should I get off my route, just look at the screen and move back to the active route. much less hassle...

You guessed right Jim, at least that is what it is in the Archive folder in my Nuvi 500. I can open the GPX with mapsource and it contains many days worth of tracks, if I haven't cleared them. When you don't clear the active tracks and you reach the size limit the Nuvi starts deleting the oldest tracks from the active group and archiving them. When there is an archive present and you clear the active tracks it will ask if you also want to clear the archive.
