Not as bad but some will remember I played satnav ping-pong with Garmin a year ago.
The 680T I finished with only charges to 99%, should not be but I live with that.as it's fairly insignificant.
The 50LMT-D had the battery become disconnected and gives the occasional very strange routing. The battery is next to useless for route planning and you have to connect it to power to route plan (I'm not a basecamp fan and don't like over using the fragile looking USB socket)
Favourite unit of mine at present for bike/walking is the second hand Monterra I bought recently, battery life and sunshine readability are better than the 680T in my view.

On powering 680 then asks you if you want to go into mass storage mode, answering no allows Montana to run normally under power.
