How to pair to a different iPhone?

Settings -> Connected Features -> Phone -> Smartphone -> <pick the phone> -> Forget

Nice friend!

Thanks for the response. Unfortunately, i don't get the options you describe.

I get Settings -> Connected Features -> Phone 

but then my options are Enable; Friendly Name; Pair Smartphone.

Enable is simply a toggle.

If i select Friendly Name, i can only change the name. There is no option to Forget

If i select Pair Smartphone, it then tries to connect to the Garmin Connect app.

I recall seeing an option to Forget before i even posted, but i've never seen it since. Maybe i was successful "forgetting", and i have a different problem now?

Since my original post, i've gotten a little further with pairing but still no joy. The app seems to recognize the Friendly Name, and the 1030 asks if it should connect to the phone. i say "yes". I've even had a code show up on both the phone and the 1030. But it still won't finish the pairing. i've tried the various steps in the app troubleshooting without success. when i have more time and patience, i'll go back through all of the troubleshooting again.

I don't want to do a reset on the 1030 since i've been using for over a year without the phone pairing. so, i'm sure i can live without the pairing.

If there isn't a phone listed, it isn't paired to a phone.

"Friendly name" refers to the 1030+ (maybe, you have more than one of them!).

Remove the "1030 Plus" items from the bluetooth devices on your phone.

I just redid it on my iPhone 16 and it worked. It asks to pair with BT and BLE.

You friend might be able to help you.
