Buttons work with cold wet fingers, which is when you need the map most.
Touchscreens fail in exactly the conditions where navigation matters. Wet fingers, thick gloves and driving rain all defeat capacitive screens, and a device you cannot operate is worse than no device because you stop to fight it. Buttons work regardless, which is the strongest argument for the 540 over its touchscreen siblings.

Garmin's routing is the other reason people pay this much. Turn-by-turn on routable maps, rather than a breadcrumb line you follow by eye, is the difference between navigating and guessing at a junction. Budget units such as the iGPSPORT BSC500 and Magene C506 now list rerouting too, so what the Garmin adds is its maps, buttons and support record rather than the feature itself.
It also pairs with the Varia radar, which for anyone linking gravel sectors with road miles is a genuine safety feature rather than a gadget, putting approaching traffic on the same screen you are already looking at. That integration is a real part of what the price buys and it is not something the budget units can replicate.
The objection is straightforward. It costs five times the competent budget units, and for a rider who mostly follows a pre-loaded GPX on known roads the extra buys convenience rather than capability. Battery life is strong but not class-leading, and the screen is small if maps are your main use.
The Verdict
The dependable choice if you can absorb the price. Button control and Garmin's routing are worth real money on a route you do not know.
