I have published photograph where I hold receiver in my hand with wire going to cluster from behind. You can get to this position without removing cluster. You can then fix receive anywhere you want behind the knee panel.

Getting to OEM spot to fix receiver with OEM bracket in the center of dash is only possible if you remove cluster, but it is still very difficult to get to to OEM spot because of space shortage.

I never tried to I install in recess behind cluster. I think audi dicided not to do it for a reason, but I have no ideal for what reason.

You can remove knee panel now before you got receiver and study the area.

Hope it helps.
