Ok so just got my first 407 (love it!) it has the standard RD4 head unit with just the basic display. My problem: I can get the trip computer to display all the time on the MFD, but when I press the end of the wiper stalk so it displays these reading on the display in between the dials it only stays on for about 15 seconds. Can this be made to display all the time. Thanks in advance for any help with this.
