RPO sound system codes / problem with axxess gmos-04
as far as i know, most hummer h2 have the UQ7 and Y91 sound system code on the sticker in the glove box.
but mine has a UQA code. does anyone know the difference between these systems?
i replaced the factory radio by a kenwood and now i got some problems with the axxess gmos-04 interface (chime does not allways work). metra says that the gmos-04 is not designed for the UQA system in a h2 and that this could be the reason for the problem?
does anyone know something about this?
thanks
