I was thinking checking the aerial connections as all the aerials worked OK on my cd400. I get a very muffled low sound with a lot of hiss so it could be the amps not powering up. Will check that on multi meter. I'm not bothered about the onstar working at the moment that's a later project. Have to see which wire powers the amps up
