iPhone 4s no longer using the speakers

[ChiaPrius]

I got an iphone 4s two months ago and the first month, the bluetooth synced fine, phone calls worked as they always had in my gen II Prius. But about 3 weeks ago, although the 4S syncs, I can't answer it on screen anymore and the sound of the caller comes through the phone's internal speaker, not the car's speakers. Callers can't hear me at all unless I have the phone to my head which defeats the purpose of bluetooth. I tried re-pairing, no change. I am mystified as to why it suddenly quit working. Anyone else having this issue?

Sounds like a strange problem, did you try to delete the 4s and re=pair it to the car? any luck or change in operation? Can you pair another cell to the car, does that work? If no, might be a dealer trip time. Just out of curiosity, are you still on the original +12 OEM battery? Quite often when that is going bad, strange things start happening to the electronics! Might want to check that out!
Good Luck, let us know what you find!!

Yes, it seems strange to me, KK6PD. I did re-pair but it didn't help. I had another cell phone that worked for many years- I'll charge it up and see what happens when I use it. When you say +12 battery, I'm assuming you mean the regular battery, not the storage batteries. I have replaced the battery, not too long ago. Thanks for your help and I'll keep you posted!

I'm having the same problem - did you ever figure it out?

Did you check on the phone. A screen pops up asking what you want to use to access the phone, car, iPhone, iPhone speaker. If it is defaulting to the iPhone and you are not seeing the phone (in your pocket) it's on the iPhone not the car.

Might pay to look at the iPhone as you access to see what screen messages you are getting. There was a an IOS upgrade a month(?) ago. It may have reset your phones defaults.

Update: I did fix it by removing all the iPhone apps I had downloaded about the time I started having the problem. First, to make sure I didn't have to go back to a blank iPhone, I saved a copy of everything to the cloud, then deleted about ten apps I suspected, totally factory reset the phone and reloaded from the cloud. It worked fine again. I'm not sure which app it was but I know I will be far more careful than I was about downloading apps. Hope this may be helpful for others.

Good for you, now I know what to do if mine freezes like yours did!
Glad you let us know!
