2006 S-Type Jag. Using an Iphone for the last year, suddenly, callers cannot hear me speaking. Every other aspect of the blue tooth system works properly. Sometimes it works, sometimes it doesn't. The dealer thinks it may be a problem with the Iphone software, but it has worked fine for the last 8 months. Seems like it may be a microphone issue or the phone module. Any ideas?

 

1st try to reboot the phone and repair it then try software and last try restoring your phone as new and remove all the apps you don't use often 9 out of 10 i phone issues is phone related

 

I've had the same thing happen to me 3 or 4 times. Try, in order.....

1. Disconnect and then re-connect phone.
2. Turn off phone and remove battery for a few seconds, replace and restart.
3. Re-pair the phone and car.
