Trouble with onstar and kenwood nav

[Jake]

So I bought a Kenwood 6019 and G510 nav. The install place is having a hard time finding the right adapter box to make all this work correctly with my onstar. What have ya'll used to make your aftermarket nav's work right? Thanks - Jake

Soundgate Digistar or Peripheral GMAH24. You might also use a Peripheral GMAH24B if you have monsoon.

They tried a sound gate digistar-x but it didn't work so we've got something else in the mail to see if it works on wednesday
