Stuck on firmware 7.19 and radar permanently disconnected

So far, I am impressed with my Solar 840. However, I have only completed 1 indoor ride and then 1 outdoor ride.

At the start of my outdoor ride yesterday I noticed my RCT715 did not transfer over to my Solar 840 from my 530. Once connected, all good. Then 2 hours in, the radar dropped out, never to reconnect. I rebooted the radar several times, rebooted the Edge 840 several times, removed the radar from the Edge 840 etc. Nothing so far is connecting them again.

I noticed I am on firmware 7.19 and 9.09 is out. I've been hitting the "Check for updates" option on the Edge 840 and it will not update.

I've since tried a full reset of my Edge 840 and again, updating to 9.09 is not happening. I don't have a Mac or Windows machine handy for Garmin Express.


Anybody else experiencing these issues?

Thanks.

    I have a 840 (non-Solar) and I didn't have any issue updating from 7.09 to 9.09. However, just like you, none of the ANT+ light network devices including my Varia RTL-515 transferred over from 530. I had to add them to the 840 as new devices. I haven't had any issue with the radar disconnecting and never reconnecting.

    Light networks are not transferable across units as the lights need to store the ID of the controlling head unit. This requires lights to be paired manually with a new unit.

    I tried resetting my 840 and still couldn't connect to my radar as it did when I was newly setting it up just a few days ago. I then, for some reason, tried holding the power button of my RCT715 (to put it in pairing mode) and bingo! We have a connection. I didn't do this the first time they connected (as I was riding when I did it).

    I hope that helps someone.

    As for the firmware update to 9.09, this would not happen when I tried and tried manually hitting the "check for updates" option. But days later (yesterday I think) the device popped up saying update 9.09 was available to install. It was seamless. I don't know why the delay, but we got there.
