The thing to remember is a good Bluetooth connection depends on the device as much as the head unit, and because the device is created to do a lot of things at once, there are many variables that can affect signal quality.Here are some basic troubleshooting steps:
- For intermittent connectivity issues, clear or “kill” all open apps on their phone. You may not realize that apps you opened a week ago can still be open and taking up memory and processing power. Get in the habit of doing this at least once per day.
- Clear the phone’s cache, then soft-reset the phone by powering it off for 2-3 minutes and turning it back on. (If applicable, remove the battery.) This allows the memory to clear and any stubborn processes to stop.
- Be sure your unit and the phone is utilizing the latest software version.
- Verify that the phone is capable of performing the requested features. Some phone models may not include the proper protocols to perform certain functions, such as audio control or phonebook upload.
- If all else fails, delete the pairing relationship on both devices, then re-pair. With the radio off, remove the radio’s profile from the phone by selecting “Unpair,” then do a soft-reset. Do the same on the radio; however, make sure the radio is on for 10-15 minutes before beginning the deletion process.
Sometimes when upgrading phones, what seems like a simple process of deleting the old phone and adding the new one can present some pretty stubborn issues.
“Marcus S.” wrote us with the following information that may be of help to others:
Here is what happened: I had a Galaxy S7 Edge (Model:: SAMSUNG-SM-G935U) When I paired that phone to the unit, it was fine, no problems.
Recently, I was just upgraded to the Galaxy S8 Plus, (Model: SAMSUNG-SM-G955U). The problem was for some reason the radio kept the G935U in the Bluetooth list. When playing Pandora, or using Bluetooth for phone calls, it would cancel the audio after 5 seconds but, maintain the connection over Bluetooth.
Issues:
- When I tried to disconnect the phone and delete the entry, the radio would not remove it from the list.
- I tried turning off the radio and re-starting it to see if that worked. I still did not remove to old entry.
- When I tried to pair the new phone, it indicated the phone was paired but it showed the older phone in the list. (G935U)
- I tried to select another open entry in the list for the new phone, but know success.
- I shut down the phone and started from fresh boot and un-paired the radio from the phone. The phone would see the radio with scanning but would not connect for first 4 tries. When It did connect, the same problem. Lost audio after 5 seconds and it still showed the old model in the list. (G935U)
Resolution:
Phone:
- Removed all paired devices from the phone: Radio, headset, and watch
- Check for updates for the new phone and made sure all firmware was up to date
- In the phone setting, I reset the Network settings
Radio:
- In the Bluetooth list, i was able to remove the old phone (G935U) from the entry list
- Paired the new phone to the radio, now the new phone appeared in the entry list. (G955U)
- Tested phone calls and Pandora. All is stable now
I believe the phone locked the hand shake between it and the radio. It could of been because I didn’t delete the old phone before paring up the new one. But once I did the updates to the phone, I was allowed to make the adjustments and all works well.
