When ever I travel from Heathrow to Kent along the M25 my 6250 routes me of the m25 at junction 6 to send me along the a22&a25 to rejoin the m25 at junction 5, this adds at least 15 minutes to my journey for no delays on the m25, I can not trust the route planner to be accurate

I have reset my devise and still the same, can this be resolved or should I replace my unit
