I just tried upgrading my Pioneer Z2 nav to the Z130bt unit in my '08 Hummer H3. I'm using the same GMOS 04 module that has been working perfectly for the last 3 years with the Z2, but with the new unit I'm getting zero audio, no system tones from the radio and no music. I am still getting the standard tones from the car through the speakers.

 

I've triple checked the rca connectors, and have checked the mute setting a hundred times....

 

Any thoughts???

 

Thanks.

i am preaty sure that aslong as you wired up the right connection then you should be fine i know the old GMOS-06 did not work right with navigation units and then maybe about 4 years ago they updated the GMOS-06 to have 4 rca plugs and other changes to let it use the navigation units

 

so the only thing i could think of is you may have an older GMOS-04 unit but then agian you had the Z naivgation in there no problem and you just want to update the unit

have you tried to plug back in your old unit to make sure it still works or maybe the harness itself got damaged doing removal or perhaps the unit you got is just bad and needs to be returned or echanged

I would try the old unit, but I'd have to rewrite the old harness back into it. I'm gonna try putting a small set of amplified speakers on the pre-outs to see if there is any output from the z130bt.

 

Are there any settings that have to be changed to tell the nav unit to send the audio to the pre outs?

sorry i am not familiar with the units as i am new to the forum

and i have a x930bt wich is my first unit from pioneer

 

i am familair with the Metra Access kits like the GMOS units and PAC interface

i actualy prefer the PAC over the Metra GMOS intefrace if it has anything to do with bose if its just for onstar and non amplafied systems that GMOS has my vote but if its a amplafied Factory system then i only go with PAC

 

all i can say is try to wire in your old unit and see if it works if it does then chances are the new unit is the problem

So that problem was a pretty easy one to fix, I forgot to connect the remote wire to trigger the Monsoon amps for the stock system.

 

Now my only real issue is with a bit of white noise unless the AV source is set to off. Any solution to this?
