Crash when loading a route [Crash 15] [Bug 146, 147]

[ConiKost]

It seems, that firmware 20.50 introduced a new bug. When loading a route via Main menu -> Where To? -> Routes, the devices will power of after a few seconds. When loading a route via Main menu -> Route planer, no power off happens.

Anyone else having similar issues?

Our Montana 750i will not properly read Routes or show them, sometimes with scrambled names, even after reloading them all to the device from archived copies.

We backdated firmware to 20.30 and Routing features work as expected again.

May wait for another update before proceeding again.

Same issues here on this firmware version - device shuts down when loading a route via find/where to but not route manager. Routes will sometimes disappear here as well. I have not yet encountered corrupted route names.

Garmin replied, that they can reproduce this and created an internal ticket.

Garmin replied and told me, that this is fixed by installing the *NTU* 2025.20 map update, which indeed fixed this.

For US users: You have to know, that Montana 7x0 shipped in europe *NT* maps, but not *NTU* maps. As Europe *NT* maps have been discontinued, Montana is now receiving *NTU* updates for Europe.
