    another quick trip for gas...

    red track is Duraforce, purple is Oregon 450. I stopped at a gas station briefly, and both units were recording tracks.

    when I remembered they were recording, I created waypoints where I sat. they weren't too far apart, so I won't fault either one for being so wrong that I couldn't navigate to them. I created 3m radius circles around those points with my phones geocaching plugin, I don't think it's possible to do it on Garmin devices....
    red circle Duraforce, purple circle Oregon:

    upon downloading the Oregon's track at home ( it can't be used with usb-otg cables and none Wi-Fi isn't available, or Bluetooth, gah!) I saw something odd.
    the green (highlighted) track shows the Garmin is very poor at "GPS bounce" or "GPS hop" that happens when sitting still for a moment/minute. its firmware isn't smart enough to realize it's just sitting still, and instead of recording a smooth track, records every change in GPS coordinates, even though they are inside it's error range. this track could still be followed of course, but if you're going to share tracks, you'll probably rib into the "my Garmin has track point count limits" and of course have to screw with the point count in basecamp to fix the errors and reduce count. sigh.
    the phone, however, didn't record extra points. the frequency settings for the Garmin were "auto" and for the Duraforce "3m and 3 sec".

    next up, a uturn.

    the highlighted track is the Duraforce, the purple track is the Oregon. I know everyone talks about poor accuracy in cities with Garmins, but dang, it really went off reservation. in not sure why it recorded all those hops for a two second uturn, but it did. it was between two tallish buildings, so maybe the multi path interference isn't handled very well in the Garmin firmware, or they just don't consider it an issue. either way, I'm curious to see how bad this becomes in the woods when I'm trying to record good gpx tracks riding single track. I'm betting it won't be usable if this is the result of a uturn.

    Are you using Locus for all this?

    yup.

    well, no that's not entirely true. I have to plug the Garmin into a desktop computer with basecamp (ugh) to get the waypoints and tracks off it, but finally after that I can use modern transfers like Wi-Fi and Bluetooth, to display both sets of tracks/waypoints on locus.

    Understand the Garmin thing. A necessary evil with Garmin is Basecamp.

    Not entirely sure where to post this, but OSM+ has been taking longer and longer to find my location when I start OSM. I have a trip tomorrow and started it tonight to check the route out. Its been taking about 10m now and still doesn't have my location yet.

    Try a different app. Something like GPS Essentials will give you lots of information about your gps connection. Maybe the device and not software..?

    Rebooted the phone and it worked. I hate doing that. I have it all saved onto an SD card, and last time I restarted the phone, I lost all my maps. I got an error that read something that wouldn't allow me to open the folder on the SD card. So I had to redownload everything.

    Worked this time though. phew

    long times to location calculation usually mean the constellation is out of date. do an a-gps refresh with gps essentials / gps status / etc and it will pick up to half a second or so.

    assuming you aren't under a mine ;-)

    Not really. There are many route designers that create GPX files.

    I'm getting back into doing a little 'real' riding after a year or two off ... yay 4 kids ... plus that Harley wasn't going to drive itself to coffee shop. Anyway, my 8 year old O.G. Zumo went away when I sold my F800GS, and now I'm thinking a smartphone should be enough for my needs. I did have some questions about that, and as usual ADV has come to the rescue. Also, as usual, there's 133 pages of jawing on the topic, with the typical ADV method; mix a few Ph.D dissertations on splitting molecules with a bit of HURR DURR DURR, add some hardware from Home Depot, let steep for 1-8 years, shake, strain into chilled glass, and garnish with some borate. Yay. I wanna add some hurr durr myself and skip ahead to the one answer I have left; is everyone just taking a glove (or two (or three? (yikes))) off when they need access to the screen? Glove-friendly is maybe a quality to miss about dedicated GPS thingers. Then again, remember browsing a map on my Zumo was something like trying to get sand out of your eye with a pipe wrench. Plus, anything easy for me to use while driving usually leads to me submitting my Darwin awards application ahead of plan ... I'm looking at you, triple-digit selfies ... and as such I'm banned from even having a tank bag. So, are there alternative control methods besides holding one glove in your armpit so it doesn't fall off or putting it on the the bars but it still falls off just out of reach and you have to put the bike on the kickstand and walk around to the other side to pick it up while everyone laughs at you? Are we attaching a stylus to our bars with velcro? Getting all Frankenstein with spare finger stashed in that stupid pocket on our jacket sleeve that nobody uses? Has Gore invented SwipeTex? Someone want to halp me out, assuage my curiosity, and enable my thread parsing lazies? Or, do I have to get all Tomb Raider on this thread to reveal the wisdom? Thx. Ps. I missed all you FFs muchly.

    So many wurdz...

    My Samsung phones S6, S8, S9 all have had a sensitivity mode that allows the glove to work.

    Kyoceras are getting expensive and obsolete.

    Search Amazon for gloves that work on touch screens. I have a pair that works OK, not quite as good as Garmin touch screen but ok.

    I believe in system redundancy i.e. just in case. I have a Garmin V for my bike and as well I carry a cell phone. I have seen instances where the Garmin has a better map or more complete map than that offered on the cellphone not to mention cell coverage.

    Mentioning cell coverage on this thread may be a call for violence.

    If by Garmin V you mean BMW Nav 5 I have many miles looking at both Nav 5 and Locus and/or Osmand, I will say they all display the same navigation information but each has it's own "personality", hard to say that one is "better" than the others. As for other info, distances to points, time to points and other info the cell phone apps have it all over Garmin for that type of info.
    I will say that I love the BMW 'wonder wheel' interface, if not for that I would not bother with anything Garmin.

    For cell coverage I have a cell phone, rarely use it for navigation, however I do use it to find commercial POIs, it is much more complete than anything Garmin at that.

    One comment I have is, I find the Nav screen much easier to read than cell phone apps. The street names are bigger and upcoming cross streets are displayed. I haven’t found an iPhone app with names big enough to read on a phone a few feet away. I have no problem following tracks on my iPhone using pocket earth pro, but routes have never worked well.i love the wheel too. Zooming in and out is easy. Trying to pinch a touchscreen with gloves is a disaster.
