Bike RADAR - for other bikes

[6zfshdb]

The whole point of these radar units is to report the location of approaching traffic from the rear, and give you an idea of how far back it is and how fast it is approaching. It does that by displaying a slider on your bike computer next to whatever screen and data that you are viewing. The radar display stays in view if you switch screens. The audio comes from the computer, not the radar.

I understand this.
I don't have a smartphone or bike computer to pair with this radar unit. I'm trying to find out if I can pair it with my Montana 700i GPS via the Ant+ function. There are mixed opinions on the web as to whether this is possible.

Yes it should, as long as it has the Ant+ function. You can order the Garmin Varia RTL515 from Amazon and return for refund if it does not work.

What ANT+ profile does a radar display use? It's not any one of the approved profiles. Do you really understand how ANT+ works?

ANT+ Profiles

The Garmin/Wahoo profile is most likely proprietary.

I'm not sure that your GPS would have the programming to display the alerts regardless of whether it can pair via ANT+.

Another option would be to pair with the phone in your pocket and send audible alerts/all clear to a bone conduction or open ear earbud.

Lezyne also has a radar system with a front light that can give you visual alerts via a red led on the back of the headlight. I think the headlight does audible as well, but can't remember at the moment. It eliminates the need for a phone or bike computer, though you are limited to just knowing whether it sees something or not.

From what I've been able to learn, the radar will simply provide an alert (tone & banner) on the Montana screen via Ant+, not the display produced on an Edge or smartphone.
I'm thinking a compatible smartwatch might be the best approach

it may not turn on and off automatically either. That's more of a function of the light than the radar.
