Garmin Xero C1 firmware update

The other day a notice came up on my Xero saying there was a firmware updated available. I looked online & all I could find about the update from Garmin was that it fixed issues. Was having any issues so I updated the firmware. I think the description of the update should have read "Causes problems" ever since I’ve done the update I’ve had nothing but issues. Inside I get a screen saying interference encountered, never had this before inside shooting in the exact same spot & nothing new that would cause interference has been added. Outside it’s missing shots, that wasn’t the case before the update. Now it seems to be real picky on placement which it wasn’t before. I wish I could go back but I don’t think that’s possible. I even did a factory reset hoping this would fix the issues, it did NOT.

If you get the notice to update your firmware, I’d recommend not doing it.

The ole adage, if it ain't broke, don't fix it, comes to mind! Maybe Garmin should adapt that philosophy! Have you contacted Garmin to see if they have any remedy for the issues you are having? Firmware updates can be a real crap shoot, especially when everything appears to be working as it should! Thank you for the heads up and I'd be interested to hear if Garmin can provide a fix for your new issues!
 
Contacted Garmin their CS was very responsive, told me the inference banner was new with the update before the Xero would just go berserk. When I told him I was shooting 11m the other day, he tells me that the Xero needs a minimum of 20 yards to work, despite that it worked before at 11m. Did offer reluctantly to send me a replacement. I agreed to do some more testing at 30 yards to see if he was right or my unit was messed up.

This afternoon I took the Reximex out, that what I was shooting when the problem arose, shot 32 shots the Xero recorded 18. It’s .177 so I tried it with the Marauder pistol Xero saw 14 out of 16. Next I tried the .177 Avenge-X Xero saw 16 out of 36.

I ask about reverting the firmware back to the old version, he tells me it can’t be done. He tells me it can’t be done. I told him it could be done, if you don’t support it just say so or send me the file & I’ll try it. They won’t give you the old file, they’d rather replace the unit. I now need to call them back & see about a replacement.

Talked to Garmin CS Tuesday and again today as they wanted me to try a few things. The results my Xero was still dropping shots and it was worse when shooting .177 cal. I was told that v3.27 was released in Sept and they have not had many complaints and I believe no exchanges. After a short conversation they agreed to exchange mine. Emailed me the details of the process, my old Xero is on its way back to Garmin. I must say Garmin CS was easy to work with.
 
I was just in my Garmin account.
If there was a needed update, they would have indicated one.
My GARMIN is from May this year.
Merry Christmas.
I bought mine in May also, don’t recall what version it was before I did the update. Garmin CS told me the update was released in late September yet I dint get the update message until December & I use it at least a couple of times a week & it‘s always connected to Shotview.

Merry Christmas
