Quick Answer: Pair a Garmin Approach R10 by holding its power button until the LED turns solid blue, then in the Garmin Golf app selecting Garmin Devices > Add Device > Approach R10 — a white flashing LED confirms success. The catch most golfers hit isn’t the pairing step itself: per Garmin’s own support forum, the R10 connects to only one device at a time, so it can’t stay linked to your phone’s app and your simulator PC simultaneously — a limitation that looks like a broken unit but isn’t. Check the Garmin Approach R10 on Amazon.

“How to pair a Garmin R10” gets searched constantly for a reason that has nothing to do with a defective unit: the radar’s single-device Bluetooth connection trips up almost everyone who tries to use it with both the Garmin Golf app on their phone and a simulator on a separate PC. This guide covers the actual pairing steps, how that single-connection limit works in practice, and how to get the R10 talking to GSPro and E6 Connect specifically.
Pairing, by the numbers
- Per Garmin’s own support forum, the Approach R10 can be paired to multiple devices but will only hold an active connection to one at a time — pairing a second device doesn’t replace the first, it just means only one can be connected at once.
- A solid blue LED means the unit is in pairing mode; a white flashing LED confirms a successful pairing, per Garmin’s documented device-add flow.
- Per golfersauthority.com’s E6 Connect troubleshooting notes, a Windows network set to “Public” instead of “Private,” or a blocked inbound rule on port 2483, accounts for a large share of “won’t connect” reports that have nothing to do with the R10’s Bluetooth pairing at all.
Step-by-step: how to pair the Garmin R10
- Put the R10 in pairing mode. Hold the power button on the back of the unit until the status LED turns solid blue. On a brand-new, never-paired R10, this happens automatically the first time it powers on.
- Open the Garmin Golf app on your phone and bring the phone close to the unit.
- From the app’s menu, select Garmin Devices > Add Device.
- Choose “Approach R10” from the device list and follow the on-screen prompts.
- Watch for a white flashing LED — that’s your confirmation the pairing completed.
If you’re re-pairing a unit that was previously linked to a different phone or PC, disable Bluetooth on that other device first — the R10 won’t hand off a connection on its own.
Garmin Approach R10
- Pairs over Bluetooth to the Garmin Golf app, GSPro, and E6 Connect — but holds only one active connection at a time.

The one-device limit that causes most “it won’t connect” complaints
This is the part that trips up more golfers than a bad pairing attempt ever does. The R10 can be paired to your phone, your simulator laptop, and a tablet — all three, if you’ve gone through the Add Device flow on each. But per Garmin’s own support forum, it will only hold an active connection to one of them at a time. Leave the Garmin Golf app open on your phone with Bluetooth on, then try to launch GSPro on your PC, and GSPro often simply can’t see the unit — not because anything is broken, but because the phone is still holding the only connection slot the R10 has. Turn Bluetooth off on the phone (or fully close the Garmin Golf app’s background connection) before switching to simulator software, and the PC picks it up immediately.
Connecting to GSPro and E6 Connect
GSPro: The R10 has to complete its initial Garmin Golf app pairing before GSPro can detect it at all — GSPro doesn’t handle first-time Bluetooth pairing itself. Once that’s done, GSPro’s own connection guide has you select the Approach R10 as the active launch monitor inside its device-connection menu. If GSPro doesn’t find it, check the single-connection limit above before assuming a setup problem.
E6 Connect (iOS): Pair the R10 to the Garmin Golf app, then from the app’s Golf Sim menu select E6 Connect and choose “Play on iOS” — this path requires an iPhone 8 or later, or an iPad Pro 1st-generation or later, running iOS 13 or newer.
E6 Connect (Windows PC): Install E6 Connect’s separate full simulator software package. If the R10 connects over Wi-Fi rather than Bluetooth and fails to link up, golfersauthority.com’s troubleshooting notes point to two fixes before anything else: switch the PC’s network profile from Public to Private in Windows settings, and open an inbound firewall rule for port 2483. Tethering to a phone’s mobile hotspot is a documented workaround when the home network itself is the problem.
The bottom line
Pairing a Garmin Approach R10 is a short process — power button to solid blue, then Garmin Devices > Add Device > Approach R10 in the app — but the real source of most pairing complaints is the unit’s one-active-connection-at-a-time Bluetooth design, not a defective radar. Before troubleshooting further, confirm nothing else (phone, tablet, another PC) is still holding that one connection slot.
