Kenwood SR 903 tuner question

[arturixtl]

Hi: I have a Kenwood SR 903 sirius tuner. I want to change my head unit
to get a better featured one. Do I have to stick with Kenwood or is this tuner compatible with any other decks: Alpine/Clarion/ Pioneer etc?
It appears to be a standard 13 pin cable but not sure.
Also: if i get a newer Kenwood excelon deck, it currently is a kdc 459 and thinking about a kdc 990 or 890..will be there compatibility issues?
thanks

I would call Kenwood to make sure, but I think your current Sirius box is for a Kenwood head unit only.
