EDIT from November 2023: I wrote this initial Garmin Edge 540 review on 23 April 2023. On the November version I just made few small text formatting fixes and edits in order to produce the Podcast .mp3 version of the article. This way anybody can listen the Podcast online, or can download it to the smartphone and listen it later offline. The long-awaited Garmin Edge 540 is finally available Worldwide! Ever since information about the new Garmin Edge 540 / 540 Solar / Edge 840 and the 840 Solar version of the bicycle computers was leaked on the Internet at the beginning of the month, I have been reading many posts with information about the parameters and capabilities of each of the four new models.
