  1. That might make some sense if you logged the serial output with a serial terminal, and got the screenshot as well. The order of the sentences might reveal something. It could even reveal that the error is in the NMEA sentences, and the GPS unit software is the problem. I haven’t done this, but expect that devices with USB (and no real serial port) act like their own serial port with the Garmin driver installed in Windows, \and could be logged with something like Hyperterminal if the serial port was enabled in the GPS device setup menu.
  2. If it’s anything other than a capacitive touch screen, which are the worst with gloves, yep When I used an iPhone I used gym gloves that have no fingers to work with hat, but not great in the cold!
  3. I don’t use it much to be honest, but have tested the same thing every update. It has gotten better, but I can still get it to crash pretty easy. I’m not talking anything new with 3.10. It was right from the start.
  4. When I first got it the day of it's arrival in Australia, fw version 2.10, it would crash browsing any map. Now I just tried, with 3.10, and it seems unlikely to crash the same way with one vector map, but will still easily crash doing the same thing if imagery is enabled as well.

    2.70 fw for GPSMAP 66

    I kept the old file. Interestingly, there’s plain ASCII text near the beginning saying “THIS SOFTWARE IS OK!”... I guess some internal message

    2.70 fw for GPSMAP 66

    Works for me I didn’t know the file was out there, thanks!
  7. Are they the black/grey ones? I have those, but never tried them. I have run into trouble with fitting six of them in a battery pack that clips to the back of a handheld radio though. It basically wouldn’t fit on the back of the radio and couldn’t be used.

    2.70 fw for GPSMAP 66

    Yeah i’ve updated fw to 3.10 too, but never seen a 2.70 GPS update. I got the info here: http://www.gpsrchive.com/GPSMAP/GPSMAP 66/index.htm
  9. Tell me you are in Queensland. I maintain domestic valve receivers already, and would probably get it going. Cheers, VK4FAST.

  11. I’m guessing that’s an older one that still has a real RS232 serial port. The 66, I found out later with help from a fellow on gpsrchive forum, does work, but whatever USB adapter used between the 66 USB micro, and serial cable USB mini, has to connect all five USB pins as USB OTG adapters would.

    New? Garmin Handhelds

    Nothing to do with GPS or EPIRBs, and everything to do with physical injury, and the fact that crystal oscillators and batteries operate within temperature margins.

    New? Garmin Handhelds

    inReach is marketed as a communicator, and transmits around 1.6 GHz as satellite phones. The 121.5 MHz IAD is for aircraft that are already within a tight radius of the beacon location, and already searching. There might not be any intelligence sent on the IAD frequency. It’s the 406 MHz transmitter that’s being received by satellites.

    2.70 fw for GPSMAP 66

    It doesn’t appear for every country at once. Not in Aus yet either.

    2.70 fw for GPSMAP 66

    Ok, it does say GPS software, but isn’t showing me anything in Garmin Express (in Australia) yet. I was able to update GPS software on it’s own when 2.10 was the only public released firmware.
  16. Hi, This was just announced on gpsrChive forum. What’s going backwards all about? As with last update, Australia will be one of the last to see it I guess.
  17. Back to talk to myself one more time. I got APRS tracking working with the GPSMAP 64st and Yaesu FT-2DR. The Yaesu CT-170 data cable was used on the radio side, and the Garmin serial cable on the GPSr side. Garmin serial cable side -----------> Yaesu CT-170 (with 2.5mm plug cut off) data cable side Red: (+) DC Power supply for Garmin GPSr. Must be powered for serial port to work Black: (-) DC Ground Green -> Cable shield (bare wire) Yellow (serial Tx) -> Red (Serial Rx) White (serial Rx) -> White (Serial Tx) ___________________________________________________________________________________________ If you don’t want to cut the CT-170 data cable, the plug’s tip is connected to the red wire, the middle ring is connected to white, and the ring terminal closest to the plug plastic body is connected to the bare wire sheild, which is ground. Both devices serial ports are true RS232 level, and can interface with each other safely by direct connection. If you find, and use this in future please drop a hello. Cheers, VK4FAST.
  18. Well if someone searches this in future, I got a USB mini to micro adapter, and tested power & data connections with other devices, and the Garmin USB serial cable didn't work with the GPSMAP66 unfortunately. I used the same interface setting as in the menu of the GPSMAP 64, and tested various serial baud rates, but saw no signal at all.
  19. I think Montana is the only larger display in a handheld.
  20. Ah I see.. weedy antenna, but probably better overall. I assume there’s some bezel outside of the screen to sit that under. Thanks for the pic. I couldn’t find anything new.
  21. That’s the whole point though. With the display facing up, as you’d normally use it, the antenna faces the ground, and all signals it sees are reflected from the ground, which would add another few wavelengths to the signal it receives from any satellite. Some vehicle trackers also do this out of necessity, because the car is above them. I can’t find current model PCBs, but these are Oregon 650 & Montanna 600.
  22. Can you take an Oregon outside face the display upward, turn it on, go to sat view, get a position, then turn it upside down with the display facing the ground and looking up at it, tell what happens? I’d be interested because all of the “all screen” units use a ceramic chip antenna pointed directly at the ground. The displays have a foil backing that would block any signal directly overhead, which is also where the chip antenna’s highest gain is. With all of the birds in the sky nowadays, it might be beneficial to block those directly overhead. I don’t know. It would also be interesting to compare them in some canyon environment where both struggle to get any signal at all.
  23. Wouldn’t have said it a month ago, but I’d rather a 66 than any of those now
  24. Hi :) My Garmin USB to serial cable arrived today: https://www.ja-gps.com.au/Garmin/nuvi-500-serial-power-cable/ I’m not associated with this shop, this is just what it is, and where I got it. The GPSMAP 64 series handheld is supposed to be supported, and I’ve tested it ok with a serial terminal program and real RS232 serial port. I suspect 66 series will work with it as well when a USB mini to USB micro adapter (on it’s way) is used, but I've yet to actually test that. The cable needs power for the GPS serial port to work, so there must be something active in that little moulded plastic block in the cable. The overall plan is to have the Garmin plot received locations (any APRS beacons) on the GPS map. Garmin specifically supported this for some Oregon and Colorado handhelds: https://garmin.blogs.com/softwareupdates/2009/06/aprs-support-in-colorado-and-oregon.html#.XNvowi97Esk Also some Nuvi support this NMEA serial input, but APRS gets little if any mention after that. I’m hoping the GPSMAP 64 and/or 66 are listening for waypoint data over the serial port as well. Will keep updated.
