i just replaced my old z1 with a new z110bt on my 2005 chevy silverado,but when i finished wiring it up i noticed that the interface module(to retain onstar, with not bose) was not putting out my 12v acc output when i turned the key on. i replaced the module with new (onstar and bose retainment) module and the stereo turned on but i had no sound from the speakers which are powered by an amplifier i had installed. i just hear the bass bumping but no sound. Does anyone think that the reason of this might be that i need a non bose module?

its the factory amp wire that needs a positive wire hooked up . i had the same problem trust me all you have to do is find the schematics for your car and it will tell you which wire to factory amp is and put power to it and wala its fixed hope this helps you and maybe you can sell me your old deck haha thanks

the only problem with that is that i am not using the bose factory amp. i have bypassed it because i am using an aftermarket amp to power my speakers.

sometime harnesses have 2 blue wires - 1 for power antenna and 1 for remote wire, make sure you have the right wire connected from your Head Unit to the Amp
