ive searched and read the process, but im not sure how to determine what model number radio i have

a best as i can tell

BMW "Professional" it has a CD player ( no stacker) 4 speakers no tweeters

i believe i have the base model E92 ( but then Base model equipment levels seem to vary based on the market they are sold in)

im in Australia, a local supplier says its a "S663 Radio BMW Professional"
\based on VIN, but when i go searching for the replacement pixel assembly i don't see that as an option.
any pointers welcomed

I went through this last year. Searched and saw a lot of instructions documenting the repair but couldn't find the part. I ended up buying a new CD73 head unit.

Most of the info is on the Stereo sub forum for this.
As the last guy said getting the part is the problem.
