No audio with BlueTooth iPhone - Sync 3

[bpifer]

Hello. My iPhone 10 is connect to the Sync 3 system. I hear no audio on incoming call. It shows the call, but no sound. The volume is up all the way on both the phone and on the radio dial. I also do not hear sound if I play music from my phone via bluetooth. Again, the phone is connected, the volumes are up and it show on my phone the song is playing.

 

I also hear no sound when using navigation. The sound on the nav screen is not muted. I tried hitting mute, and unmuting and no sound. Please help.

Hi bpifer. More information would help. You do not mention the model and model year of your vehicle is, what version of SYNC 3 is installed in your vehicle (e.g. SYNC 3.0.xxxxx, SYNC 3.4.xxxxx etc.). Also, how long have you owned the vehicle, and when did this issue begin? Did your phone originally perform properly via SYNC, then suddenly stop working? Or did it never work properly?

 

Can tell you this: If your vehicle has SYNC 3.0, you need to connect your iPhone via cable to utilize Apple CarPlay, play music from your phone etc. You can not play music from an iPhone via Bluetooth with versions of SYNC 3.0.

 

I am not sure why you are having the other volume issues. I would suggest performing a SYNC master reset, then reconnecting your phone.

 

If that does not help, and your vehicle is still within the New Vehicle Warranty period (or an ESP that covers electronics etc.), you should make a service appointment to have this issue properly diagnosed and corrected.

 

Perhaps other forum members may have some suggestions which may help.

 

Keep us updated and good luck.

My apologies. I have a 2015 Ford Fusion. This is an upgrade from a Sync 2 system, to a Sync 3. I have Sync 3.4 My phone connects via bluetooth or CarPlay, but the sound from music or phone calls has never worked.

 

I tried connecting via a cable and was able to see CarPlay working on the screen. It shows a call come in but no sound. I shows a song is playing but no sound (through the speakers).

 

Same with the navigation, it runs on the screen, but when it goes to give and audio direction, the radio goes quiet, but there is no sound from the navigation itself.

 

The radio itself plays fine, I hear sound no problem. 

 

I did a master reset and nothing changed. Same issues.

Hi bpifer. This is the problem with "upgrading" to SYNC 3.4 from SYNC 3.0, Ford MyTouch, LincolnMyTouch, SYNC 1 etc. There are almost always some type of issue and/or features which do not work properly, and the usual troubleshooting does not work. Since this installation is a third party/aftermarket update to SYNC 3.4 (as opposed to the original factory SYNC installation your car had), there are now too many variables involved.

 

For example, what APIM and hardware did you install? One from a SYNC 3.0 vehicle or a SYNC 3.4 vehicle? Used...new?

 

Did you upgrade to SYNC 3.4 using the CyanLabs website tutorials? If yes, it may be best to contact them. If one carefully reads the caveats that CyanLabs lists, there are certain features which often will not work after a SYNC 3.4 "upgrade" like this. Since you have had this problem from the very beginning after "upgrading", this may be a hard issue to resolve.

 

At this point, if you used CyanLabs, contacting them through Email (or text...if available) may be your best course of action. They have probably seen this problem before and may have a work around.Sorry I can not offer much more guidance, since normal troubleshooting will not work in this case.

 

Perhaps another member will jump in with some ideas.

 

Keep us updated and good luck.
