I have been having a conversation with Garmin support about using the RTL510 with my Edge Explore as there seems to be no way to activate night flash mode either manually or automatically from the Edge.
I was interested to receive the following:
The Auto setting will only adjust the intensity of the light on compatible devices.
The RTL510 was designed specifically to work with the edge 1030.
Also the Edge Explore was designed to be an entry level device and not all Varia functions will be available.
The Edge doesn’t have a light sensor but is does know sunset/sunrise so surely it could use that? (The manual specifically says it uses ‘ambient light and time of day’.
I think Garmin should make it a lot clearer what functions are supported for each combination of devices. The Explore has clearly been designed to work with the Varia lights, it has a dedicated screen to control them and the radar display works perfectly.
