I searched but was unable to find a satisfactory answer. Here is my question/problem. I have a basically bone stock F700BT the only "mod" is the pin out change to allow use of all functions without the parking brake. I purchased and installed 3.0 update from Pioneer.

Things were going swimmingly with no major issues until about a month ago, now when I try to place calls, the call drops off. I am able to place the call from the contacts list, the phone (LG shine CU720) initializes and places the call, I hear it ring, but when the person on the other end picks up it drops the call and hangs up my phone. It is very frustrating and incredibly annoying. Anyone have any ideas or can point me in a direction to troubleshoot this issue?

 

Thanks
