I might be wrong but.........
I haven't read anything about XC hours but if you are revalidating you will need to fly a mini nav exercise.
I revalidated recently after a long lay-off and part of the process was to plan a flight as prescribed by the examiner. About 15 mins into the flight I was asked to divert and give ETA and new headings etc. Once I was over the designated point then that was the end of the nav bit and it was back to some stalls, steep turns and PFLs etc.
