Forza Horizon 2 Fast & Furious Missing 5 Reward Boards

As the thing says I am missing 5 rewards boards. When I look in Progress it says I have 15 of 20 but none of them are highlighted. I have the xbox one version. Can anyone tell me if 5 of them are hidden and if so where should I go to find the locations. Any help you can give is appreciated.


is there a way to tell which ones I am missing I have never used it before or do I just need to do a map comparison I did figure out now I have 19 out of 20 but the last one down in niece is messing with me. Update found it
