I have a 2010 Prius and have an awful issue with pairing my IPHONE 4 with the car--- I switched carriers from AT&T to Verizon for better signal and had to upgrade my phone to 4 from the 3GS. I had no issue with the old phone, but the new one drops connection constantly... no one seems to know how to fix this problem and I am unsure of what to do.... I did want to stay with the APPLE phones... it that possible??? PLease let me know if anyone has had the same issues.... thanks so much!
