I just bought Drivesmart 66 but I noticed it not have the History icon (History channel)
Are you referring to “HISTORY points of interest?"
In the manual - Garmin DriveSmart 55/65/71 Owner's Manual - Finding HISTORY Points of Interest. Garmin states...
This feature is not available on all product models or for all map regions.
If you're wondering why your specific model doesn't have it, I suggest reaching out to Product Support through their website at https://support.garmin.com.
