Con wasn't talking about a normal phone but the rugged versions of phones and tablets. They perform under Hush conditions like you mentioned.
If you compare an Garmin XT 3 to my T865X tablet it will be quite obvious that mine is not alone better but its multifunctional

I wasn't aware that there is a "rugged" version" of an iPhone. And on the Android side, the rugged versions of phones I've researched don't provide the full functionality of regular phones for everyday use. As far as tablets, they're too overwhelming for my BMW dash area, even if I wanted to do the surgery necessary for shoehorning it on.

HW aside, I outlined many functional areas where the MRA phone app (or any phone app) does not provide the functionality of the XT3. This is simple fact. Con asked why anyone would consider a Garmin, and this more than anything else is the primary reason.

BTW, do you own an XT3 and use it to is full capabilities?

why would you prefer a locked-in old-design one-purpose device over a modern flexible rugged and much cheaper phone or tablet? To be honest I can think of only one thing: glove operation. Which can be overcome with the right gloves or a remote control.

I can think of many reasons, from the perspective of a Garmin XT3......

At the physical device level. The Garmin doesn't overheat. It can tolerate Death Valley USA level heat and other abuses that a phone can't. Additionally, the Garmin screen is completely readable in glare, while the phone isn't.

Operationally, the Garmin utilizes 3D terrain maps that put any phone app to shame. It's like operating a video game watching you route progress through mountains, canyons and valleys. One of the crown jewels of the device are the dynamically captured Trip Data metrics which can be selected in different combinations and displayed on the screen. Another cool feature is the ability to start a secondary route to an unplanned search point and then easily restart your main route when you reach that destination. All of this happens without altering your main route at all. Then there are the off-route recalculation options that are a completely different subject.

Is the Garmin a one-purpose device? To a degree. I prefer to call it a specialized device that can perform navigation at the highest functional level. This isn't a knock on the MRA app specifically. Phones simply have limitations. If your navigation requirements exceed those limitations, the Garmin is your device.

Ideally, you mount your Phone and the Garmin side-by-side (I do). Then you get the best of all worlds to cover most possible situations
