Anybody know how to access Codes on NAV equipped 540i? I've heard that this system allows TV reception in Europe -- maybe just a rumor.
Also, what are the test functions brought up by placing Key in position 1 and pushing Odometer Reset and CHECK control for 4-5 seconds. There's 21 tests - cycle through by pushing CHECK and start/advance by pushing ODO.
What do all the tests do? Are they the same as the tests for my M3 E-36 OBC-II?
Any hackers out there?
