I have difficulty configuring the echo problem I have during calls made from my iPhone4 using Sony MEX-BT3900U Car Audio System. I followed the instructions regarding the echo and noise reduction, but yet the echo remains. What am I doing wrong? Can anyone help?
iPhone 4, iOS 5.0.1, Sony MEX-BT3900U Bluetooth CarAudio
Same problem I use a iphone 3gs and gives echo sound too.
Read lots of reviews and seems not a issue just wondering if the unit has a fault or as above what might I might be doing wrong ??
