Sensor error radar 0:9

I encountered this error today on my Edge 530/Varia RTL516 (version 3.32) for the first time.

Occured 2 times during my 2H ride today.

Garmin , wake up and fix this bug !!!

I had this occur on my edge 530 after a firmware update.  I removed and readded the Varia and it seems to have resolved the issue...at least for now.  May be worth a try unless you've tried it already.  

I tried to remove/readded radar but still the same error !

please Garmin, do something !

I tried the same, still get the error. Getting really annoyed of it now. 

I have the same error several times during my first 2 rides on my garmin 1030 with my RTL515...

I encountered this error today on my Edge 830/Varia RTL515 (version 3.32) for the first time. Occurred 2 times during my 2:30H ride today.

Première sortie hier avec le Varia 515 neuf couplé au compteur Edge1030

Erreur 09 trois fois en 4 heures plutôt en fin de sortie. Les routes étant humides et sales, le Varia était très couvert de débris divers. Cela peut il être la cause de l'erreur ?

Same issue for me : often at the beginning of the ride and then sometimes during the ride (Edge 1030 ... generally it disappears after a few 10seconds... I tried to clean a bit the radar because some droplets of water/mud were on its surface but it did not change anything... I was wondering if the traffic radars would interfer with the Varia radar ?

Is it possible to update the firmware of the RTL515 ?

another one here with the same problem...
