How to change settings to flash lights when remote unlocking

I have a 2009 E89 sDrive23i autobox used as second car. I want to set up the remote locking to flash indicators when unlocking so I can locate car in a crowded car park (like today in Portsmouth or tomorrow at Goodwood Revival.) I read the manual and it tells me turn on ignition & toggle buttons 1 & 2 on indicator lever until you get to SET then go to a setting showing the setup. Every time I tried that it got to either the time or date setup and no further. Any ideas where I'm going wrong? Thanks in advance. Shaun Coles

I just had the same thing!

Found if you have the car running (engine on) then you get all the options and not just the time/date setting!
