This past weekend I was out of the area and really happy with off-course features when I had to re-route due to smoke from a grass fire. It is not perfect, as it kept trying to put me back on course but eventually it was shorter to continue on my new road and it realized that and stopped trying to put me back on course. There were only 3 roads along a canyon to the ocean (high, mid, low) so it was impossible to get lost. Also I forgot to create a route on RideWithGPS (free - desktop) or Strava (well not anymore, didn’t pay for premium after trial ended). Just before leaving used Garmin Connect mobile for the first time to create a route. Never used that feature before so I fumbled around for a couple minutes, then tapped out the route and synced it to the 530.
If buying again I’d be tempted to buy the 830 for touchscreen, but for the price the 530 packs a lot of useful features. I’m of the opinion that a bike computer is an expendable item, so price/features/performance was tops in my decision making. I’ve been in the software industry for 30 years, both Garmin and Wahoo have annoyances but in different areas. Someday I may give Stages Dash a try, it looks somewhat interesting.
