[Talk-us] Whole-US Garmin Map update - 2018-07-03

[Elliott Plack]

Thanks for sending the alternatives and blog! The Edge is a small-ish
screen bike computer. the 820 was until a few days ago in the newest
generation so I was surprised at how sluggish it was with the OSM maps.

Here's a link to the default cycle routing map it uses, clearly OSM Based.
They don't update as frequently but must do some QA/QC on the data.

There is a setting for map detail, but it didn't seem to hide much of what
was bogging down the rendering, e.g. buildings, addresses, etc.
