I've had success when sharing a map location when starting in google maps, haven't tried directly from the Mercedes maps. So did a share of google directions to Mercedes me app, which then says it is sent to car and then shortly afterwards received it in car. It wasn't instant probably about 30-60 secs or so after turning ignition on MBUX popped a notification of it. Only used it twice, but has worked so far.
