GPS optional
steptronic is automatic , sport automatic , sequential manual selection , gear stick has PRND on the console , whilst in D you could shift lever to side gate labeled M/S + / -
the instrument cluster will show indicated mode selection so when in D if you move lever to the side the instrument will indicate D S , indicating auto sport mode . if you then move gear stick back this will sequentially upshift , if you move stick forward it will sequentially downshift . once you manually select a gear the transmission is in manual mode until D is selected .
if you buy an X5 be sure to read the handbook for all operating procedures .
there is a cool thread on this site you will find using the search function at top of page titled cool hidden features of the X5 .
good luck
