A retractable hardtop assembly is provided for a vehicle. A retractable hardtop assembly includes a front section that is connected by a linkage to a vehicle and a rearward portion that is connected by a separate linkage to a decklid of the vehicle. A package shelf/tonneau is secured by a linkage to the back section of the linkage. The package shelf/tonneau is moved from a package/shelf position below the rearward portion of the roof to a tonneau position above the retractable roof when the retractable roof is disposed in the storage compartment. The package shelf/tonneau is moved between the front portion of the roof and rearward portion of the roof during the extension and retraction cycles. The package shelf/tonneau may be rotated 360° as it is moved between the package shelf and tonneau positions.
