I’ll be contacting Apple but I just upgraded my iPhone from Original to 4 and when I’m in my car there is a loud clicking noise whenever I make a call. Both parties hear it and it’s not good. I have a 2005 Stype STR (Super charged) and on the Jag forums there are many other users, many model years, now posting the same issues! I do not have Navigation in my car, some others do.

My original iPhone I had for years with no noise?????

 

Help.
