I don't want my giant ass phone in the sun on the handlebars where it's going to get smashed the moment I take a tumble. The battery dies way too fast leaving the screen on, it overheats, it's fragile...etc.
250 for a dedicated bike computer was an easy buy for me. It compartmentalizes my electronic needs for the bike to this one device instead of making my phone do something else it doesn't need to do.
I have a dashcam in my car too. Why have that when my phone has a camera and an app?
If you do not understand the need for a cycling computer, just leave the thread. Seriously, stop posting the same BS in all of these threads. People who use bike computers do not care about your uninformed opinion. Go away.
For people who are interested in the device, note it's the same cost direct from Garmin and shipping is free, so if you can afford to wait a few extra days, that's a good way to support the company directly!
If not tracking power and cadence, is it really worth getting a dedicated cycling computer over just using my phone for music and the occasional routing?
Up to you.

because this is $249 and not $1000+ if nothing else. If you are competing you do not want your phone getting smashed if you crash do you? Also a phone battery with GPS on and the screen on in the woods is going to in an hour. This thing will go for like 8 hrs on one charge; and there are models with solar that top off the batter in the sun. Lets put it this way; if you have to ask the question then you will not need one.

Bike computers are mostly for real-time monitoring. Yes, they can provide map guidance for commuting and whatnot, but it is not their primary function, especially for the lower end units with small capacity that do not store the maps in themselves, but are more of a proxy display and need your phone for planning new routes. AFAIK the 540 is still in this category, with the 840 becoming able to work independently (still needs you to have regions pe-downloaded into it, it doesn't have cellular data for this to happen on the road, but latest 5xx and 8xx series can use your phone data to do it on the-go too).
If you area to monitor additional information, this is just the head-unit with the GPS trackers and storage etc. You will need additional sensors, like a Power meter (this includes cadence almost always built-into it), or a heart-rate-sensor, or cadence sensor etc. The head unit is part of an ecosystem, typicaly with decent cross-compatibility (ANT+ or Bluetooth) between sensors and bike computers of different manufacturers).
Why is this better than your phone?
Eh, debatable depending on how often and long you are riding with it on, type of terrain and how rough you ride, but objectively battery life is in a different league, the display is easier to read under the sun, they are far less prone to over-heating under the sun, more robust (it is not a good idea to mount high-end phones though a rigid mount on bike handlebars, even on bikes with suspension forks, as vibrations tend to f-up image stabilasation and/or focus mechanisms on flaship phones that have these. Happens on iPhones a lot, did happen to me personally on a Galaxy Note 20).

No its not. I really do not understand why people buy these things, especially at such a cost. You can buy a dedicated GPS system for a car at half that price. Why are these so much more expensive?
The GPS inside your car isn't exposed to the elements, it's inside a car. It's also plugged in, not running on batteries for half a day at a time. Half the tools that end up listed on this site cost less than the batteries they need to function; batteries are expensive. It's also a brand name, Garmin.. what's the cheapest Garmin unit for inside a car? You are likely playing at least $100 there, likely 2-3x that, which is mostly for their software/map access.
$250 is more than reasonable for this if you need maps while riding a bike. Personally, I use my phone along with an Apple watch for direction but my watch easily costs just as much. If I wanted to keep track of things like cadence, or wanted something not dependent on cellular, there's an argument right there for this.

This is the first time the 540 solar has hit the same price as the regular 540. If you have a 530, this will let you do TWO target metrics during a structured workout. I'm actually bitter that's locked behind a hardware wall when my old wahoo elemnt v1 could give me a target cadence and heart rate without any issue.
