I like my garmin edge 1040, I like where garmin stop the timer when you come to a full stop. What I don’t like is the outside temperature reads 8 to 10 degrees higher then the actual temperature, it is useless.
The Edge 1040 has great battery life. I am well versed in using it and moving it from bike to bike. It has two flaws. First, it does not connect to an Apple Watch - I use the garmin chest strap for HR and it works great but is uncomfortable. Second, The Edge recalculates route information it receives from Garmin Connect. This results in dramatically conflicting data all within the Garmin ecosystem system. There is not one truth! I was uploading a route on Alpe D’Huez and Connect said a 3800 foot climb and the Edge recalculated it to 8,000 foot climb. It did this multiple times, I did a factory reset and it still was wrong. (The correct height is 3800 feet.) When this fails I will likely look away from Garmin
The tocuh screen is not reliable. Sometimes it works, other times it does not. The other scary problem is taht pretty frequently, the 1040 does not power up. This also happens when you need to shut it down. The boot up process is unreliable & inconsistent. I am up to date with all software updtes. The device is so buggy. By far my worst Garmin device I have ever had. And I have had plenty of Garmin devices.
Love this more than the other two Garmin's that I have used. Love the screen size as it makes it less challenging for me to see the numbers when I am moving. My eyesight is not the best so this makes it easier to not have to either slow down or be distracted. Amazed how all of my sensors automatically were detected when I was setting up the unit when it arrived. Only knock I would have is my Varia I have to turn it on where with my 530 it always turned it on for me, but that it really not an issue, just something that I have to either remember or stop shortly after I start when I realize that I forgot.
I never ride my bike without my Garmin 1040. It tells me speed, time, distance, lets me answer phone calls, tells me direction. I totally love it! Plus along with my other Garmin device I know when cars are nearby. Totally love it
