I bought my 2011 Kia Forte several months ago and have experienced continual issues with connecting my iPhone 4 through the KIA factory dock connector. While my iPhone is connected, the audio unit will start whistling randomly while driving, will reboot, or will switch into bluetooth and start altering bluetooth settings without prompting (such as language or pairing). This occurs only while the iphone is connected and while driving, whether during bluetooth calls, radio use, or iphone music use. I've taken the car in for service several times over the past for months to resolve this which is included a swap to a completely new audio unit with no change. The KIA company has now told me the car is only intended for iPods and was never intended for use with iPhones (despite the irony that the iPod touch is that same operating platform). This also has occured with my girlfriends iPhone 4S. Has anyone else experienced this issue or similar problems with any devices? KIA has told me that I should just use the bluetooth (which sounds horrible by comparison) and that they have no responsibility for this problem and will not correct it.
