I got my Z1 installed yesterday and on the way home i tested the onstar to see if it was working and when i hit the button, it turned off the z1 and the onstar voice was going nuts.

any thought on why this would happen?

other than that, I love the Z1!!! the ipod is a little slow and it took a little while to get the blue tooth volume right on the phone, but still an awesome part!

You need to be a little more specific than going nuts. I'm guessing by your s/n that its in a vette. What year? What's the model number of the interface used?

no, its in my 2006 silverado.

when i hit the onstar button, the z1 shuts down and the onstar voice starts calling off all of the commands for the hands free phone.

Did you also get a steering wheel control interface, like the SWIPS?

Did you also get a steering wheel control interface, like the SWIPS?

yes, but it isnt intalled yet.

hopfully tomorrow.

Which interface did you use? If you don't have the steering wheel interface hooked up yet, there is no reason that the OnStar should do that, outside of installer error or a vehicle malfunction.

after some time yesterday, we got it all worked out.

the onstar works like it should, the pac-swi-ps works like it should and the day/night works on the screen after much work to find a wire to tap into on the newer gm wiring harness.

its nice to have everything working and still retain the factory look and feel!
