CD Player (Sirius Compatible?)

[bd3500]

Hello,

I have a 2002 X5 3.0i manufactured before 10/02 with the stock Business In Dash CD player (No Nav / No DSP). I would like to add OEM Sirius but am having a hard time finding which CD Players are compatible. Is there a site that lists which cd players are compatible?

I notice there are a lot of Alpine CD players on ebay with square holes, but looking at the production date of the cd players on ebay that most claim to be aux/sirius compatible have production dates of 09/2000 or 11/2000... What gives?

Also, is there a magic formula in matching up which sirius receiver works with which cd player?

Thanks!
