me!
i thought i was the only one so i never posted about it.
that issue has happened over a dozen times since my delivery in november 2014. it occurs intermittently and without reason. the system would revert back to the settings that the car was on when it was last started (i.e. the radio station goes back to the one it was on when the car was started).
i've taken my f80 to my dealer 3 times now.
1st appointment) the first time:
"performed a scooe and a test plan. reconfigured the most-bus and checked the operation of the idrive."
<no signal occurs again>
2nd appointment) did a diagnosis and determined that the car needed another appointment to do some programming.
"short tested. performed energy diagnosis - load tested passed. 12.68v avr tested 14.1 v charging followed test plan for fault patterns needs updated software and coding. service measure."
3rd appointment) "programmed and encoded complete vehicle including headunit to update software level. customer to monitor."
<no signal occurs again>
need to go in again for another diagnosis and a possible replacement of the headunit. still haven't had the time to go in yet. i hope this helps you.
