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

UQA - Sound system feature, Bose performance-enhanced premium 9-speaker system

Y91 is the Bose LUX option

UQ7 Appears to be the NAV option

thanks.

i knew the codes but did not know what was meant by them.

in other words, does that mean that i have the bose standard system while the Y91 is the bose premium system?
