Just got the Edge 830 and have used the 800 for over 10 years which was a great little device. However, I wanted to move up the tech ladder mainly to support Varia light/radar and later di2. So far I am not impressed. The low level of sound is terrible. My Vaira is in the mail and I am now concerned with reading so many posts about the volume I am going to have issues with notifications from the radar unit. How could Garmin let this happen as I have to think it should be an easy fix to a potentially major safety issue? My 800 had good sound levels even with the speaker in the middle of the quarter-turn mount. I have to think there have been or still/should be some lawsuits regarding this terrible design flaw by Garmin. Someone is going to have a bad accident because they never heard the notification. Garmin, please either statically increase the volume or make it variable with a control. Also, I have noticed I am missing several on the bike notifications that I always had like start route beep, power-on beep, auto-stop and auto-resume alerts. Is this normal or just more flaws or omissions in the software? I am just so disappointed in what could have been a favorable and more safe product upgrade for me. Thinking about returning it all.
