Correct. It is Arabellapark at the end of the U4 (my clue "ballpark area" being an anagram)
Its just the signs you need to figure out now (which are by no means Unique to that station- I would suspect that they are at every U-Bahn station in the city). The answer will come from someone who has noticed them in Munich or another German city using them, or from someone thinking laterally and extending from Grahame's very nearly right answer.
If you could zoom into the sign you might not yet get the answer (depending on your grasp of german). If you want to cheat and see a closeup at a different station click on

I used to stay at the Sheraton hotel in Arabella park so used that ****damn station every mon-fri for six months!
But it was July 07-Dec 07 before I saw came across this sight - ie before the hellish TT change!
Mondays: Flughaven to Leuchtenbergring
Daily - if pissing down - Leuchtenbergring to Arabellapark - if dry - walked it - damn site quicker given the two changes
Friday: Leuchtenbergring to Flughaven
I used to have memorized the german for "the next station is XXXXX, please alight the train from the left/right hand side" without knowing what it meant!
