you could down load the map and the Garmin will tell you when the turn is coming up
920xt I have never used any of those functions. Great idea!
dude... i hadn't used any of those functions until this year. game changer... but i suggest a dedicated bike gps computer. check the lezyne super gps. sub $200 and last 24 hours!!!! has ALL the functions!
Would save me a ton of time and wrong turns out here on these gravel country roads. Every ride latelt has been like an AR staring at the map and stopping!
