Garmin 3597 LMTHD and BaseCamp

I have been comparing the 3597 to my 1490LMT. Limited test but the GPS as a stand along GPS is much improved. The unit design is Apple all the way but clearly the Nuvi firmware group don't talk to any other group. Touch screen is much more responsive. Split screen for junction views is great. Voice directions are improved. Searching google on your iPhone and blue toothing the info is really helpful. 3D dem maps are included for use with CN maps. Lots of really cool stuff on the unit.

When it comes to BaseCamp it seems clear to me the Nuvi firmware group does not intend to support BaseCamp. Example: Legacy file system.

Both my Dakotas allow me to delete geo data (waypoints, tracks, and routes) from BC. To delete geo data on the 3597, I have to go to Trips and delete routes, go to save data to delete waypoints, go to settings, device, and clear travel history. I have not upload a track from base camp to see where it would show up. In addition I have to mount the GPS volume on the desktop go to the GPX folder and delete all files I fine there plus empty the trash.

I am sure the nuvi firmware group is saying Nuvi users don't use BC. Any why should the spend hours creating a customized route if they can't load it to the GPS without getting a different route. I can and will continue to use BC with my Nuvi, I can make it work pretty well, but when the casual user starts seeing routes in BC on the device they can't see on the device, they probable blame BC.

The verdict is still our on Recalculation of routes but it is not look good. I just uploaded 9 routes and BC noted the routes were calculated from CN 2013.4 but the 3597 has 2014.1 and BC ask if I wanted to recalculate. I said no and it takes forever but I have 9 Routes in Trips and they match the uploaded routes perfectly. All routes I have tested start for my home and I am at a different location now. Different from the 1490, the 3597 does not ask me where to start from, it starts from my current location. When I hit go the route gets recalculated and I want to be home to be totally sure but I think the route will change depending on the 3597 route settings. I will keep trying but it done look like the nuvi group is talking to the zoom/Montana group.

    Is there a better method for deleting data from the Nuvi 3597 than the method described below?

    On the 3597, I delete waypoints form Saved (used to be favorites) button, Routes from the Trip Planner app, and I ususally go to device and clear historical data (tracks). When I go to Saved on the Nuvi, it tells me no data available. When I go to the Trips app, it tells me no saved Trips (used to be routes). When I connect the Nuvi to BC, and select the Nuvi 3597 under Devices, I see waypoints and routes I just deleted. The two waypoints were uploaded to the Nuvi by dragging the route created from the two points.

    If I open the Nuvi mounted volume on the desktop, go to GPX folder and Delete Temp.GPX the waypoints and route will not appear when I start BC. I think Position.gpx stores my set home location. and current.gpx puts a blue flag 001 waypoint at your current position. See screen shots below.

    Is there an easier way to keep the deleted routes from building on the Nuvi? My 1490 does not have the option to delete (really just hides) uploaded routes on the GPS, I think it automatically starts replacing the first route uploaded after 10 routes.

    Thanks

    To delete all you need to delete any gpx file in the GPX folder.

    temp.gpx will invariably be a gpx file sent by Basecamp to your nuvi. Anything in it is merged into your nuvi every time you boot, so if you don't delete it the items in there just keep coming back :)

    Incidentally it's position.gpx that puts the blue flag there, and it's your last location when you removed your device from the cradle with power on. It is saved as a single Favorite.

    I keep loosing my Home setting. I was hopping current.gpx or Position.gpx contained my home setting but I only removed temp.gpx and the Home setting is gone. Thanks for the position.gpx information. Sounds like it might be a good way to find you car if you carry your GPS.

    Home position if set on your GPS will be in current.gpx ... At least it always has been AFAIK and I've just checked my current.gpx and it contains my home info. I don't understand how deleting any gpx file could delete it. Even deleting current.gpx file won't actually delete anything off the GPS as it's recreated from data held in inaccessible memory every time you switch on your nuvi.

    Are you following the instruction at Page 3 of the manual to set your home location?

    That is certainly true on every nuvi I know of. It is not true on the Oregon x50 and other models. On those current.gpx only contains the active track log. Waypoints and saved/archive tracks are saved in other GPX files. If you delete any of those files the data is removed from the unit (after the next reboot).

    That mechanism is how BaseCamp (or other software) deletes data from the unit. Perhaps the 3597LMTHD has a similar mechanism (?) even though PSEABOLT doesn't think it does.

    The GPS in question is a Nuvi 3597. The menu is different from my 1490. When I tap Where TO and home button it gives me 3 options to set home location. Once I set it, the next time I tap Where TO and Home, I am routed home. The home button seems to be working and in the past I have been deleting everything in the GPX folder. In the example I posted in the thread there was not a current.gpx file in the folder. To evaluate the new Nuvi, I have been deleting everything before each outing. I bet the hope location is stored in the Temp.gpx file if that file has been created and no Current.gpx file is in the folder.

    Thanks

    Yes I know this thread is about the 3597. However I don't own one nor do I have access to one.

    What I'm trying to point out is that it may (I don't know) not work the same as earlier nuvi models. I don't know its files structure.

    For example on my Oregon 450 its

    \Garmin\GPX
    \Garmin\GPX\Archive
    \Garmin\GPX\Current

    There may be a current.gpx file (somewhere) on the 3597 or maybe not. You'll have to figure that out and what's in it.

    BTW many of those technicalities are defined in the \Garmin\GarminDevice.xml file. That's how BaseCamp, and other Garmin software, know how to read/write data from/to the unit.

    Well as I understand it current.gpx is written after a nuvi boots, having merged any other gpx file in the GPX folder with what the nuvi holds in internal inaccessible memory. In otherwords it's a one way copy of what is held there. Of course as Stuart says the 3507 series could be different, but I've seen nothing to indicate that is so.

    Also, on previous nuvis (certainly since the 13xx series) when you set a Home location a Favorite (saved place) is created called Home and that appears in current.gpx (if it's been created). If you've deleted all the files in the GPX folder, then rebooted your nuvi, and it is creating a current.gpx and a temp.gpx file then that's certainly a change, even more so if temp.gpx contains your home location.

    temp.gpx in the past has been 'reserved' for applications like Basecamp that use temp.gpx as the filename for data that it sends to a nuvi :confused:
