I needed the mounting frame for my new Sony radio that the implanted from the factory radio in my Fiat Bravo II, replaced. Since double DIN probably not always double din, I initially had problems my radio to assemble without wobbling. The existing framework, or the one who came with the Sony were once too large, even too small. Only this frame helped !! One must indeed squeeze gently but firmly into the mounting hole him, but if he then sits times, then he sits without similar wiggle Even the accompanying black frame fit very well into the gap between the frame and radio. Some of mounting accessories was also doing so well, everyone can find something suitable to attach the frame completely in the opening (was not necessary for me, because the frame so firmly in the "hole" is sitting, that there can no longer move) Only the two the two metal parts to unlock the radio (if it needs to get out) are very unstable and bend way too easily. But ok, as often is a radio not installed and removed. The frame is certainly worth the money and help where this problem occurs, the radio exchange.
