Varia Radar and Audio Prompts

Been using the radar with my 520 for a year, and it's always worked very well. Recently switched to the 820 and I'm using the navigation audio alerts (paired with iPhone/GC mobile), but unfortunately the radar alerts are not transmitted through the phone app. I find the alerts from the 820 are difficult to hear, especially when I'm getting audio alerts via an earpiece.

Anyone know of a way to have the radar alerts also transmit with the other audio prompts into the earpiece (via GC app)?

    Does not appear to be at the moment.

    One of my favourite features of the 820 is the audio alerts (I currently use Average Speed & HR), but it's a shame that Garmin bothered to implement fully. I have reminders set for 10 minutes and 5 miles they would be better as audio alerts and the warning beeps from the Varia/820 are useless above about 15mph, these could all be fed into my earpiece via my phone.

    I have just spoken with Garmin rep. He was 99% sure that radar head unit has audible beeps *after* firmware update to *both* radar unit and light. Can anyone who has this bundle confirm? Thank you very much in advance!

    radar does indeed beep when it detects something approaching fast (10Kph faster than your speed) but alerts are not carried through earpiece if you are connected to a phone... (sound of edge 820 can be difficult to hear if there is a lot of wind)

    note that it won't beep for every car though: it won't beep again if cars keep appearing at a close interval, and cars coming up slower won't be detected at all.

    I think it's a good behaviour: this forces me to keep paying attention if there is some traffic, but will wake me up when I've been riding on a quiet road for a while and a car approaches fast.

    Thank you and apologies, i posted accidentally in the wrong thread (I knew there was one, but I couldn't quickly find it). I should have posted there:

    oh, sorry, I somehow missed the fact that you were talking about the head unit... I do not own this one, but if you check the video below, at around 3:00, the reviewer clearly states that there is no speaker in the unit...

  • Apologies for any confusion. The Varia Rearview Radar head unit only shows lights to indicate approaching vehicles and does not provide audible tones.

    Yes, that is what I thought! Someone should tell Rick at Garmin Support team that :)

    I whole-heartedly agree that there needs to be an audible alert through the phone. The 820 is effectively inaudible. The display is cool, but will not get your attention if you're not looking at the cycling computer, and it's just not wise to ride along the road staring at your cycling computer.

    Getting my attention that there's a vehicle approaching seems to be at least half the value proposition of this device, and without alerts from my phone, it just doesn't get my attention.

    [I have both and I can 100% confirm there is no audio beep in the head unit, nor in my Garmin Edge 820 from the rear radar unit, nor in my headphones connected to my iPhone and the Connect app. All firmware up to date. It's amazing Garmin doesn't think this is a priority after all the posts on this. It should be simple at least to put a beep through the app to headphones/iphone. Other audio signals are given - like turn signals, etc.]
