I still cannot get my contacts and preset messages to sync to the Montana. I need to call Garmin Support about that...or just enter them manually.
I also purchased Garmin's HuntView for Arizona online, and downloaded it rather than buying the chip.
I fiddled around with this as well. I was unable to sync the contacts via the same methods as the other inReach devices I've used by clicking 'sync' on the explore.garmin.com site. It says on that site you can use Express to sync but that doesn't sync the inReach information.
I installed the Garmin Explore app on my phone. It's, essentially, the same function as Garmin Earthmate that I used with my inReach Mini. You'll need to pair the Montana to your phone using Garmin Connect (which will automatically open, if installed, when you try to pair using Explore). I had it installed since I used it with my Mini. Don't do like me and click cancel when it asks you to pick an accessory during the pairing process. It will take a minute or two for the Montana to show up in that list. Once paired, you can sync all your inReach stuff via the Explore app.
I found the explore.garmin.com map online and the map in the Explore app to show a particular hunting easement while none of the other Garmin maps showed it. I asked Garmin about this and they suggested the huntview chip. I asked about download vs chip and he said both need a chip. The advantage of buying the chip is that it can be moved to different devices. If you use the download and Garmin Express he said it becomes locked to the device so I went ahead and ordered a chip. I asked if he could verify that the easement would show up but he could not. It's very strange that the Explore map would show it but no other map I could find.
I guess I will install the Explorer app on my phone and see if I can get the contacts and preset messages to sync...thanks for that tip.
Where did you guys buy huntview at?
