Montana 700i keeps turning off

Not really , i.e. friday I had a shut down and it was battery powered . But I keep using it the whole weekend (tree days) and no more turning off. I´ve never used the powered mount because I have no one. I powered some times on micro-USB port and I have had random shut downs but although I´ve tried to find a pattern I´ve accepted that it is randomly. I thought it happen when it started to recalculate a route while navigating but it wasn´t , other time I thought it was due to full transient memory  something like RAM memory, butcann´t confirm anything.

It´s really frustrating that a very good GPS turns into a crap due to software , becouse when I bought it it doesn't happen, it wasn´t till 13.X firmware , I think, it started to do that.

The fact is that Garmin software team is absolutely unuseful, some times solves something but at same time they generate other bugs, i.e. last firmware cause a missreading battery charge, at least in my case. I´m so exausted , that I don't care to pass anything to Garmin support. In my case I have accepted a crossfingers to no have any other stupid bug that make my GPS unuseful.

As a Hardware Montana 700 is a very good GPS, fast, good screen and good battery, but when a rugged phone at half price reach 1000 nits, I´m absolutely  confident my hair will not goes white before that, I´ll sell this crap and I´ll turn back to my GPSmap 62 as a spare sistem  and it will be hard , very hard I´ll buy another Garmin product.

Hi there. I see your post is from 2 years ago.. I have a new unit and it too randomly switches off. 
i am disappointed to see garmin says they are working on it from 6 months ago.. yet I too have this problem in Sept 2023? I am not confident to take it on truly out of the way places 

What firmware do you have? I just updated to the latest 18 something and now it has been on for two days. Fingers crossed!

I've got first unexpected shutdown on 18.10 today.

maybe interesting contaxt: was riding under low-hanging power lines.

Reported to Leslie.

Powered mount.

Received RMA'd 700 replacement two weeks ago and have been riding almost every day - no auto shutdowns encountered yet!

Have switched off auto-pause and auto-start. Powered mount. 

Fingers crossed the last unit was a lemon. 

Garmin very rarely produces a lemon. Their hardware is world class. Most issues are either user error or software related. 

Garmin is like Apple - hw/sw.

Last unit failed multiple times. New unit no failures so far. Same s/w.

Please explain. 

I do agree their Montana 7xx s/w needs maturing. 680 is still the stalwart, rock solid.

PS - Monterra was a failure.

PPS - H/w / s/w who cares. It's still a failure if it fails. 

Tried Tread, XT2 also. 

Has anyone successfully found or had their Montana repaired yet?  I'm kinda aggravated that this problem has been going on so long.  It clearly isn't on Garmins priority list.  I've got another out of country trip planned in a few months and feel like I need to purchase another product while my Montana collects dust!  What good is it if it can't be trusted?

Why it shouldnt be trusted?

At least my unit.. update to newest firmare.. shutdowns itself rarely.
