alfagt1963 Posted May 22, 2010 Report Share Posted May 22, 2010 Hi all, Just installed my Avic F900bt into my Alfa Romeo GT with Bose sound system. I have set the master and voice volume to maximum but they are still not as loud as the system volume, if I set the volume to make the GPS voice volume loud enough then the radio volume is too loud. Is there any way to sync the volumes or to adjust the GPS volume. Thanks Quote Link to post Share on other sites
alfagt1963 Posted May 23, 2010 Author Report Share Posted May 23, 2010 Problem sorted!! I wired my system using the RCA outputs connected to my Bose amplifier, I had to set the volume to about 45/50 to get a decent sound level. I am now using the standard speaker outputs connected to my Bose amplifier and the volume level is about 10/15 and the satnav voices and phone volumes are working perfectly. Apparently the Pioneer RCA outputs are about 2v and the Bose amplifier requires 4v to attain a decent volume level. Hope this helps others Regards Mark Quote Link to post Share on other sites
