Garmin 810 and dynamo power
« on: March 22, 2015, 06:04:20 pm »
So I now have garmin 810, Luxos U lamp and Schmidt dynamo hub. All works well together, the garmin even charges when the headlamp is on (didn't expect that).
There is one issue I'm wrestling with- uncovered halfway back on the Kennet audax.
When the USB power drops (either chache battery is empty at rest, or going slow up hill) the garmin gives warning the external power has been lost, and I then have 15 seconds to clear it or it then powers off.
can this be prevented?
1. by a garmin setting (auto power down makes no difference)
2. by a different cabling setup
3. something else
