    ok I am a dummy when it comes to gps never had one and know nothing about them. I just ordered a garmin 172 and it comes with a bluechart base map.....my question is do I need to order a blue chart south central inland lakes to go with it......or it that already in cluded in the base map?

    and are they hard to use
