This looks like a huge forum so i hope someone can help, and that I posted this in the right place...

I have avn726e, installed professionally. Jeep Grand Cherokee 05. I have iphone 3gs. Everthing works except I can not hear the caller on a phone call. They can hear me fine.

FYI...I can play music via bluetooth. Could this be a connection issue (cable)? Is it an iphone issue?

Help??
