After toyota replaced the radio i still had the same problem.Finally the bluetooth on the car would find the katana but could no longer connect to phone.I put my h700 headset on and same problem.found the phone but couldnt connect to it. I took the phone to the sprint store and it didnt pass the tests and they replaced it. Now no more problems
The bluetooth works fine 99% of the time,only problem is when under high tension lines and i expect it to have problems then.
