I find the bolt very good for following a pre-set route but any variation to that route and trying to find it again, find the start of a route, etc involves pulling your phone out unlike the Garmin where you had a reasonable chance of using the map on the device to find where you were going.
I have OSMAND on my phone for those no reception areas where you need to re-route which isn't ideal but does the job.
