Hi there,
Thanks for the feedback. Please apply gentle force to align the middle part, ensuring that the two pieces do not overlap after installed. By default, the two pieces may overlap when assembled, but with gentle force, you can align the middle part to ensure they do not overlap. This adjustment is essential for securing the sunshade stably onto the roof.
If you encounter any difficulties aligning the two pieces, please don't hesitate to reach out to contact@vion.parts. If possible, sharing a video demonstrating the alignment issue would be greatly appreciated and helpful for troubleshooting.
