Garmin 780 RV “sharp curves”
Any way to increase the threshold of what Garmin considers “sharp”? The gentlest bend generates a warning so as a true hazard alert it’s useless. Also I’ve disabled it in the driver alerts settin...

Most of the data for "curves," clearance etc. is derived from data that states/counties/etc. have in data bases for roads. so what one place considers sharp another might not. Add to that that some localities for tunnels have the edge clearance as the reference rather than lane clearance height. So i've found that GPS units, give clearance issues when there really isn't an issue.
As an example SR14 in western oregon tunnel clearance on the GPS was listed such that I didn't have clearance, yet I know that it is a common route for trucks and often used as the alternate route when I-84 is close. Driving down the road, yup, many clearance signs show the edge radius clearance outside the traffic lane NOT the overhead lane clearance.
The old "garbage in garbage out".
