Garmin Montana 650t suddenly missing important part.

[+GOT GPS?]

I was trying to get the old Montana 650t GPS charged up and connected, and everything was working until this morning when I noticed that the Power Button is missing. All I see now is a microswitch inside on the circuit board.

 

Now I am wondering if I should get a Montana 700 or a GPSMap 67, since I have the iPhone 13 Pro.??

I could keep the GPSMap 64st, or is it worth it, to upgrade to GPSMap 67 with long battery life?

 

No I see that the Montana 650t was from the Summer of 2011, and the GPSMap 64st was from 2014, so that one is supported with the latest firmware, to work with Garmin Explore App and website.

 

P. S. - I have been a Very long time away from Geocaching, GPS units, and even lack of hiking. The Smartphone and Internet to blame.
