I used this map (got it from some one in QP)when I went last month, It was a big help May god bless you.... I just got confused while getting back from Madina.... after Riyad I missed up where to get to (Al-Kharj) exit, when asked some one told me to exit at No.30 any ways I managed after reaching indst. area of Al-Kharj, I turned on my mobile GPS.....and poff I'm in DOHA...:)
