Orranje has developed this Sony Head Unit Surround, to allow the fitment of the Sony XAV-AX5550D to your R50, R52 and R53. This adaptor allows the Sony head unit to securely fasten to the OEM head unit recess, and surrounds the Sony head unit in an OEM looking finish - made from injection moulded plastic in the UK; no rough 3D printing here!
Please note fitment requires modification to your R50 R52 R53 head unit surround and down tubes to fit.
