Hi Garmin Matthew, can you tell us, when we can expect an new error-free update for our Garmin 820? 1 day, 1 week, 1month? It would help us in our decisions.

Even my Edge Explorer with v12.30 loses all the sensors, cadence, FC and Edge Remote Control, I also went back to v12.10 and everything works.

I have the same problem. Device isn't stable. Keeps trying to "go to sleep" whilst navigating a route. Device won't maintain connection with Varia Light or PowerTap powermeter (no problems before). This update has effectively bricked this device. Mine is within warranty, so I am going to try and get a refund through the Consumer Rights Act - Garmin appear to have made my 820 "unfit for purpose". They also appear to have known about this for 4 days without a fix. Is anyone else losing patience with Garmin?

Hi Garmin

It would seem that people are manually rolling back to version 12.10.

Is it possible for you to send out version 12.10 as an update whilst you are working on the bug in version 12.30?

I have the same problem as you. I have problems with the heart FC, cadence and speed sensors. The value appears and disappears every 2 minutes an the record of the values is not correct. The calories are bad calculated because the value of heart sensor disappear.

It is a problem with the version 12.3 of the software.

@Garmin: We need that you solve this issue updating the software as soon as possible!

Hi there, I tried reverting to previous version and I am having all kinds of issues. When can we expect a fix?

This is very frustrating, honestly never expected a company like Garmin releasing a version that creates more problem than doing any good

Exact same issue. I have 4 x bikes all with garmin cadence sensors, upgraded to 12.30 last week on my edge 820. Sensors connect but then return zero data to the display, or erroneous data, or works okay for 15 minutes then blank. This is common to all 4 sensors. Tried deleting and reconnecting every sensor but this did not solve the issue. SORT THIS OUT GARMIN!!!! Amateur behaviour and no way to treat customers who have invested heavily in your ecosystem.
