I have a Z2 that I'm using a can-bus module with, with the navagation, and bluetooth the volume is so low you can't hardly hear it, yet it's turned up all the way. All other functions FM/CD/Sirius all have great volume. Any suggestions

on the can bus module is a potentiometer(little round knob with flat head screw head) turn the radio up 3/4 of the way and match the sound output to the radio and can module.

I'll try it out, thanks

cool and just so you know set the potentiometer with the can interface exactly where it goes i had trouble with a toyota one shifting sound when moving it today.

Well what I did I bypassed the factory amp, and wired my speakers into the z2, using its amp, and now the volumes are all good

yeah that works too
