I tried your problem and work for me, but has a small delay 2-3 sec..
Tested with samsung phone KK 4.4.4 and lenovo tablet JB 4.1.2 installed on sd card both..
If the iGO is closed goes to selected point normally..
If the iGO is open in background, yes the first screen show the last point and after 2-3 sec delay go to new point.
please try again and wait..
