Shouldn't a 67i set to Expedition Mode remain in Expedition Mode?

Shouldn't a 67i set to Expedition Mode remain there?  After a recent startling loss of energy remaining in my 67i battery, I discovered that when the device receives an InReach message, it switches to full power mode and remains there until reset back into Expedition Mode.  Is there a reason for that?  I'm pretty sure the device was not designed to trick users into depleting their battery on a long expedition.  I use the "Prompted" setting for Expedition Mode.  This is especially troubling since the device (contrary to the manual's explanation of LED codes) shows the same single-flash code whether the device is in Expedition Mode or in full power mode.

  • Will someone with a 67i help me run a comparison?  

    As twolpert suggested, I opened a support ticket.  Garmin support could not duplicate the issue. So it may be unique to my unit, but I'm not convinced.  If someone here with a 67i would try to reproduce the issue I'd appreciate the confirmation.

    Generally, the comparison involves configuring the 67i to match my settings, putting it in Expedition Mode, sending an InReach message to it, waiting, then checking its state after the message is received.  

    Settings Menu:

    • Expedition Mode setting should be "Prompted".
    • Display settings (first two in order) "1 Minute", "Off".
    • Bluetooth setting (first two in order) "Connected", "Show".
    • WiFi setting disabled, i.e. "Off".
    • Tracking settings (in order) "Off", "Off", "1 Hour".
    • Messages settings (in order) "Off", "On", "Off".
    • Recording (in order) "Auto", "Normal", "Off", "Off", "Hiking" 
      • Advanced Setup (in order) "Fit and GPX", "Daily", "During Activity", "Activity and Trip"

    Home Menu:

    • Tracking (Irididium) set to "Off"
    • Recording off, i.e. not recording.
    • InReach Utilities shows a "Last Check" time, i.e. it is not "Checking".  There's no up arrow at the top of the display.

    To Test

    1. Put the 67i into Expedition Mode by pressing the power button for a few seconds then selecting Expedition Mode.  The display will go dark.  The LED will single-flash green.
    2. Change location of unit.  A stationary unit in Expedition Mode may not check for messages.  This is an unrelated issue.
    3. Place the unit where it has a reasonable view of the sky.
    4. Now that it is in Expedition Mode, from a smartphone or MapShare page send an InReach message to it.
    5. Wait.  Don't do anything until the LED double-flashes green signaling that the message has been received.  Because the unit is in Expedition Mode, this might take a few hours.
    6. Now that the 67i has received the message, it will either be in Expedition Mode or it will be in the higher power mode.  In either case, the display will be dark.  Do not touch the power button.  Pressing it would put the 67i in high power mode and invalidate the test.  Instead, press one of the keys on the face.  If the display turns on, the 67i is in high power consumption mode.  If the display does not come on, the 67i is still in low power Expedition Mode.
    7. That's all I want to know.  Was it still in Expedition Mode or did it switch to high power mode?
  • I just found this, did you get it resolved or do you still need help?

  • No,ChristineF, nothing has changed since the last post on August 2, 2024. Despite Garmin Support’s failure to duplicate this issue on another 67i, I still suspect the problem is a firmware bug. But I have only one device. So I don’t know if other devices would behave the same.

  • Sorry to hear, that sucks... I'd love to help but am getting on a plane tonight and then will be going to Iceland for a hike on Saturday, and I'm super busy until then. So I could only do it when I'm back on Sep 1st... If that would help? 

  • Yes, ChristineF, that would help. I don't expect the uncertainty to be cleared this month.  If the issue affects all 67i's (not just mine), it will only matter to someone leaving the grid for more than two or three days who doesn't know about the potential to drain the battery or someone (like me) who leaves the grid for several days and for whom the few ounces of an external battery pack matter. 

    Such people can work around this issue by taking a backup charger containing about 11 Whr (11 * Watts * Hours) and the necessary USB cable.  I think the energy capacity of the 67i battery is 9.3 Whr. (Please post a correction if that 9.2 Whr is wrong.)  If your 67i battery is depleted as a result of this issue, recharge the 67i to no more than 1/3 of its capacity so that you still have reserve energy in the backup charger in case the 67i battery is drained again.  External batteries almost always have the energy capacity printed on them somewhere, but they are often marketed by Ahr (Amperes * Hours). Hopefully, the Ahr number is based on about 3.6 V (Volts). The 9.3 Whr equals about 2.6 Ah * 3.7V, but some energy is lost in the transfer.  So an external battery advertised at 3 Ahr should have about 11 Whr and barely charge the 67i to almost full capacity. 

  • The battery of the GPSMAP 67i is a 3.8V 3100mAh battery, so a 11,78 Wh capacity.

  • I believe 67i firmware update 8.80 solved this problem but introduced new complexities regarding InReach communication while in expedition mode.  I'll start a new thread, "Does 67i update 8.80 affect InReach communication in expedition mode?" to avoid confusion.

  • Hi! I have gpsmap67 (without InReach) and my device just keeps waking up from Expedition mode. It's very frustrating when you are off the grid. I contacted Garmin support and waiting for reply 

  • Hi, Os.  As I said earlier in this thread, I believe this "wake up" problem as you called it was corrected on my 67i in the version 8.80 update.  So if you're lucky, your 67 may be fixed soon with a firmware update.  Fingers crossed.
