Our 2011 Hyundai Santa Fe suddenly has Bluetooth problems, when turned on the stereo will connect to our phone and will be able to play music for about 40 seconds before stopping. The stereo acts as if the phone is still connected but can not interact with the device- phone calls and voice commands do not work, and then stereo menu does not respond as in it cannot change the device it’s connected to, cannot delete devices and so forth. Then if left alone, after about 5 minutes the Bluetooth will spontaneously reconnect and play music for another 40 seconds before the cycle repeats again. We have tried resetting the fuse and deleting and reconnecting the phone from the memory (which works when the car is initially turned on). Anyone else having this problem or know of a fix, or will we have to replace the stupid thing?
