Issue with phone

Just to clarify. If you pick up your phone and call your son he can hear you just fine. If you are in the truck and use the hands free Nav system which is linked to your phone you son cannot hear your? This problem only occurs when calling your son through the Nav system and everybody else can hear you just fine calling through the Nav system?

Here's what I would try if it was my system.

• Write down all your sons contact information on your phone.
• Delete your sons contact out of the phone.
• Reboot your phone.
• Sync your phone to your truck and access the phone book.
• Call someone from your nav system.
• Reboot the phone again.
• Add your son back into your contacts.
• Call your son
• Sync your phone with your Nav system.
• Call your son from the truck to test.
