Anyone else using their phone via Bluetooth, and having to constantly rebind the phone with the car? Half the time I have to delete the phone from the car's infotainment system and rebind it to use the hands free system in the car. When it does, it's great. All my contacts show up, and conversations sound great over the stereo system. But the car constantly drops the phone, and the process repeats.

for me, if the Bluetooth fails, it's the phone that is at fault. which has been rare. works for a very high percent without issue. as for paring, I've only done it once when I first got the car.

only have the one phone paired with the Bolt.

I've had this with my iPhone 7, latest firmware. Plugged in to CarPlay bluetooth disconnects and all works fine over the wire. When not plugged in Bluetooth connects/disconnects at random intervals. Infotainment is at 14.5.0 - no issues with this phone in my previous daily driver, a 2007 Prius, or my wife's current 2009 Murano.

I don't have the problem the OP does, but I have noticed after I call up SIRI, the onstar wifi says it's connected (again) a few seconds later... every...single....time.

I used Bluetooth for a drive today for the first time due to CarPlay refusing to work. (iOS 12 beta issue) I found the volume to be very low, requiring me to crank it up significantly to hear anything. Volume on phone was maxed too. Anyone else experience that? It could very well be a beta issue as well hah.

I have the same issue except I use Android Auto with my Samsung S9. When plugged in my volume and sound quality is very good. If I'm lazy and just using Bluetooth I have to crank the volume considerably to listen to music from my phone.

In early days (about 15 months ago), I had terrible problems with my phone (Nexus 6p) dropping all the time. I tried one of my old phones (an HTC M8), same issues. Did factory resets, RMAd the Nexus. None of it helped. Turned off the hotspot in the car, and the problems went away. This was an easy choice for me, as my phone has better coverage in my area (Verizon vs. ATT), and the data rates weren't that attractive. I haven't had a single BT issue since then.



Why would this make a difference? Some WiFi (802.11 b.g.n) and BT operate in the same band (2.4 gHz), and a poorly implemented BT in a phone can get swamped by a strong WiFi signal. My 2 phones happened to be known for poor BT implementations. YMMV.

Huh! So far, the last three starts, my phone has connected to the car, or vice versa, every time, since just power cycling the phone after getting them to pair again by deleting the phone from the system. Fingers crossed, this solves my problem.

I was next going to try turning off the car's WiFi, but that hasn't so far been necessary. How does one do that, btw? Just curious. In case I need that info for future use.

very interesting. because I turned off my car's hotspot months ago...

I didn't mean to suggest that this was the root cause of any/all BT problems in the Bolt, just mine with my phones. I was pretty careful to only change one variable at a time, but there might be other environmental factors (sunspots, solar wind :)) that might affect the region I drive in that I would be unaware of.

You forgot phase of the moon, and number of one dollar bills with five ones in the serial number in your pocket.>:)

All good input. Cheers.

I think I figured out my problem. I'd been getting this occasional warning graphic at the top of the infotainment screen. I could never figure out what it was by the time it disappeared. It was so brief. Are those....keys? What is that? And I never figured it out until now. It was telling me not to put my phone in the wireless charging cradle. My Bluetooth flip phone is not wireless charging capable, and the system was detecting something metallic in the charging cradle, and was trying to tell me "Hey doofus, take your keys or whatever out of my charge cradle!"

Of course, the cradle was probably doing something weird to the phone, and/or the Bluetooth signal, and was screwing things up. I've since moved the phone to the pocket designed for an old garage door opener. Phone connects every time now, it's out of sight, and every thing works.

Don't put anything metallic that ain't a wireless charge phone in that cradle.

Same volume issue here with my Note8.

By the way, the Bluetooth connection has been very reliable.

I get the warning icons when placing a phone that has wireless charging.


the manual is interesting, implying that objects only are an issue when the phone is charging:

Remove all objects from the charging pocket before charging your mobile phone. Objects, such as coins, keys, rings, paper clips, or cards, between the mobile phone and the charger will become very hot. On the rare occasion that the charging system does not detect an object, and the object gets wedged between the mobile phone and the charger, remove the mobile phone and allow the object to cool before removing it from the charging pocket, to prevent burns.
