I have a 2010 Prius without bluetooth. I use the AUX jack a lot for my music but can't for talking on the phone like I use to in my Jeep. When I'm on the phone through the aux any person I talk to hears their voice echo. I tried raising and lowering the speaker volume on my phone and on my radio- this just creates feedback. I called Apple- they said it's not a problem on their end, but the aux jack might not be compatible with the phone. They told me to call Toyota. Toyota said it's not on their end. Any ideas? If there was no ideas how to fix this, does anyone know if the $200 iPod/iPhone integration kit (cheaper than a ticket for talking on phone!) fix this- I assume this would work through my satellite button on the radio? HELP!!! Thanks everyone.
