[mkgmap-dev] Routing Issue with Garmin Edge 830

Thu May 21 10:34:31 BST 2020

Hi

Setting tag mkgmap:unpaved can have an effect on routing. The default
style sets this in response to various highway types and surface,
tracktype, mtp_scale, sac_scale values.

My garmin devices have a routing option to 'Avoid unpaved roads'
