i don't use bluetooth myself in the car...BUT i know a lot of work has been put into SynergyROM and bluetooth issues...might want to check it out...no promises...but i know the devs have worked hard to make it work

you can see the changelog since the ROM went to nightly status...there are quite a few entries regarding bluetooth so it might be worth checking out

Yep, rumor has it that is now fixed in the latest R50 ver of Synergy. YMMV.

 

Depends on what bug. Running CleanRom 1.3 and I do not have to enter the ping every time I connect to a device.

 

I have a similar issue and wonder if its my stuff or the norm for this phone:

Upon a reboot or re-enabling Bluetooth, I have to manually connect (not pair again; it remains paired) my Plantronics headpiece by pressing the button on it. This is the first phone I've had this issue; I haven't found an option to automatically connect to paired BT devices.

Am I missing something? Because that's pretty asinine.

 

I've even had that with my gnex now that you mention it. I don't use BT that often so I never really thought about it. But even though my device maintains the pairing with my speaker set, I need to hit connect to get it to .. well connect. However, when I get into the car which has BT it auto connects. Or it did with the gnex, haven't tried it on this yet. I will in about 2 weeks when I travel and get the car again.

Have you tried it on a car BT?

 

I don't have a car BT--well, besides Torque, which does automatically connect to my BT OBD-II scanner.

I use my Plantronics earpiece 99% of the time.

 

Maybe it's a problem with your car's bluetooth? Mine connects just fine when I get in the car.

 

I use the Plantronics Voyager Pro and I've had to manually connect to my work phone Razr Maxx, my Gnex. Not all of the time, but it does happen a lot. I can't find the headset, so i haven't tried it with the GS3 yet.

 

I have no issue with my car Bluetooth or a Bluetooth headset with my stock Vz S3. Connects every time as soon as the BT devices power on.
