I just bought a 2008 Mazda 3 S Grand Touring with the 6 speaker BOSE system. Whenever I try to use the AUX input to play my iPhone the bass frequency drops in and out when I start driving. I have tested it with the ALC on and off and it happens regardless. The bass frequency pops back in whenever I hit the volume control or any other button but then will eventually drop back out. This does not happen, however when I am just listening to the regular radio. I know there have been numerous posts with similar problems , but mine only drops in and out when I'm using my AUX input.
Does anyone else have this problem? Anyone have an ideas on how to help? IS there a service bulletin for this? I'm very confused and frustrated with this. Please help friends!
