tried that - didn;t work at all!!
Have since tried other mobiles - and they suffer the same problems too!
Im convinced its got soemthign to do with the fact that I am running the stereo through the pre-outs to my amplifier....
is there a way to hook up a separate speaker to the HU to try and boost the volume - was thinking of one of those speakers in the footwell that used to come with older incar handsfree kits???
