my experince using PPG PRO .
no matter how , the map will show u r in jln p ramlee whenever u open the apps . than try this .
go to map view .
wait for a sound " searching for satelite signal " until " satelite search complete ...
than u click function button under the screen . tap current position . yr position only able to locked now .
than u may start use navi to POI or any road .
p/s activate 3G network will help alot on position locking via satelite .
must use under clear sky . best to mount yr iphone on windshield .
so far , PPG quite good . quite accurate , routing fast .
only disadvantages so far is .. the things dunno shortcut ....only ask u follow main road .....
It should know shortcut. Try setting the routing to the faster way or something. currently its set to ways which are easier for cars to drive on
