  • Garmin GPS III Plus date problem

    Hi Guys.

    I have a GARMIN GPS III (not plus), and I had the 1995 problem (mine was showing may) that you seem to have.

    I discovered it could be a combination of the Y2K bug, and the End of Week problem. Apparently around in 1999, the way GPS was operating needed to be updated, so they changed a few things in the method. The End-Of Week issue was solved by an update for GARMIN GPS units (including the GPS III).

    I found a link at http://home.mira.net/~gnb/gps/gps38.html that (near the bottom) spoke about the end-of-week problem. The Readme file from Garmin (and the Zip file) are linked, but it links to:

    Zip File:

    I know this says GPS38, but it seems it was a generic problem in many units (one program to fix all), and the software seems OK on my GPS III

    I had the serial cable for the PC, so I powered up my GPS, attached it to the computer, and ran the GPSEOW file on my PC. After I got the serial port working in (COM1 - COM4, rather than COM5 I had by default), it connected, and updated my GPS. It now has Jan 2015 (correctly)!

    It does need to autolocate after the update, so having an antenna and the sky handy is useful, but that seemed to behave OK after it got a fix.

    So, even with my Win8.1 PC, and a USB-Serial adapter in 2015. I can get it to update fine.

    Hope that helps someone else.

  • etrex30 warnings

    Are you using a Route and a routeable map? It sounds like you are. If so and you set the via point to " dose not alert" it won't alert the point however it will still alert you to turns. If you go into "setup" then "Tones" then "Early Turn Waring" and "Final Turn Warning" you can set them both to off. You can also go into "Proximity Alarms" from the tone menu.Then turn on "Proximity Tones" you can set tones or turn them off for "Proximity Alarm", "Approaching Proximity Alarm" and "Leaving Proximity Alarm". Then from the main menu go into "Waypoint manager" Select the waypoint you would like to alarm by pushing in on the joy stick. Then push the "menu" button then go into "Set Proximity" You can then set how close you would like to be when it alarms.
  • Micro Disk for Garmin Nuvi 50LM?

    I did create a lot of "weeds"........ <<grin>> I just can't help myself, sometimes tangent paths are to irresistible for me.
  • Can Garmin 51LM saved trips be sorted?

    Well if you have the patience you can sort them by scheduling the trip, scheduled trips are sorted in time order so a trip scheduled to start at, for example, 1000 will appear after a trip with an earlier scheduled time.
  • express not recognising nuvi

    tried my Nuvi 2797via one of these meters plugged into my USB3 port with a fully charged GPS and it shows 4.85V with a current starting at 0.880A (880 mA) settling down to 770mA.
    That could be a hefty drain on many a computer port and it is recommended that the GPS be fully charged before connecting to a PC.
    Lowering the screen brilliance to about 50% reduced the consumption to 330mA, this could be a simple solution if power consumption is the issue.
    I will do a bit more experimentation as I have experienced many false start attempting Nuvi connect to W10 and just persevered, maybe it is time to track it down.

  • Garmin eTrex - Creating a trail map using track recordings

    It seems a bit strange to me that it cannot be more accurate though!
    It will not seem strange if you become more familiar with the technology. Garmin's handheld devices are accurate to within about +/- 5 meters (16 feet). And Garmin claims +/- 3 meter (10 foot) accuracy for the GLO. Think about what these numbers mean. If you go to a marked location and record your position two times, those points will (theoretically) be within 5 meters of the true location. However, one of the points could be 5 meters north of the actual location, and another could be 5 meters South. So, the distance between two points recorded at the exact same location could be 10 meters (33 feet) and the GPS would be within its specifications. You can see this graphically in the image I posted (and the thread about accuracy I linked to).

    If you are trying to map a trail that is only 1 meter wide, that is a huge error. But, such are the limits of consumer devices. None of them (including the GLO) were designed for making precise maps of small areas. Want more accuracy, no problem. SXblue makes some nice bluetooth receivers with sub-meter - or even centimeter - accuracy. Cost is in the $3000 to $7000 range

    https://sxbluegps.com

    Trimble is considered the "gold standard" for highly accurate GPS receivers. Expect to pay in the same range, although you may find some in the $2000 range.

    https://geospatial.trimble.com/GIS

    These are professional tools where no trade-offs have been made to keep the price low enough to appeal to a mass audience. There are other bluetooth receivers in the consumer space you might consider however, such as Bad Elf

    https://bad-elf.com/collections/bluetooth-gps

    and Dual

    https://gps.dualav.com/explore-by-product?category=GPS

    I considered these two companies when I got my glo a number of years ago, but felt they did not offer any advantages at that time. Things may have changed today, so you might want to do your own research.
  • Garmins Overlander GPS

    Hi all...

    Am finally home after some 4700 miles bumming around: Nevada, Idaho, Montana, Wyoming and Colorado. The $$$$ Overlander in my opinion did very well especially the "Explore" (topographic maps). Once you get to your destination within 50 miles the topo will come into play as well does the "Drive" where it lists all "Ultimate Public Campground" without commercial RV Camp sides. Although you can still access commercial RV campgrounds by choosing "PlanRV Parks".

    While "Ultimate Public Campgrounds" are fine, many so called "dispersed" are often not there but simply are pull over sides from the main the road or even NOT accessible/closed. Garmin Updates ???!

    While driving under "Drive" the Overlander does show many upcoming campground sites: NFS, BLM, State. Some campgrounds are not there while the Overlander says its there!

    We set our GPS not to use Interstates, the Overlander often gives us largely exaggerated long back roads although there are still some shorter routes available. Many routes might not be shown on "Drive" through the mountains but is available by reading your paper charts.... so one uses the topo which shows the route but no distance indication-no campground indication-no time of travel needed to end of road indication. Many rural side roads are also private access roads.

    The suction cup does just fine and always needs to be "re-sucted" each morning. The magnetic connection never failed even on very rough roads.

    So far so good...

    Cheers...

  • Garmin introduces the Montana 750i

    I wonder how on Earth Garmin tests these units prior to production runs. The 276CX ran like a slug, obvious the first and last time I used it. Now the next premium model the 700 series seems not bright enough unless the transflective screen is lit up by direct sunlight.

    Guess the 680T is going to stay on the bars a bit longer!

  • Next Garmin software / map updates?

    Dedicated GPS devices are a slowly dying product category. It has been going on for many years and no doubt will continue until the inevitable end. :(
  • Navteq maps - paved footpath routes?

    Well that's a strange question ...

    If you know the route from your home to the town centre is there any need for you to worry about this?
