Have you saved, both in GT5 and GT Acadamy, shut down your PS3, restart PS3 & check for system update, then start GT5, (which should automatically advise of an update if needed) then log into GT mode. It should be under the Community - Gifts section, where you claim the vehicle, then it will move to your car trailer, where you claim it just like any other award vehicle.
As well, just to be clear, you got gold in all 5 events for round 1?
