Digistar-B Problem

[markw]

Hi,

I'm replacing the stock head unit, but want to keep the Bose amp in my 2004 H2. I fitted a Soundgate Digistar-B interface but get no chimes and no sound from the new headunit. The interface is very easy to install as it comes with factory connectors so I am certain that I didn't make any mistakes with the installation. I switched back to the factory radio and everything worked OK, so I know the amp and speaker still work. I'm guessing the Digistar-B that I have is broken, or is not compatible with the Bose amp...

Has anyone else fitted this interface? The installation instructions state that there is an issue with 2004 GM vehicles with option UQ7, but I don't think my truck has this.

Thanks,
Mark.
