I have been trying to get into Radio Service Mode but just can't get that service menu. I have found three great postings with three different methods. Which seem to get their steps from BMW technical document tp://www.bimmerboard.com/forums/posts/154948/.

When I follow the steps in the firsts 2 examples by holding the SELECT button I breifly see on-screen 'PRES ON'. After it disappears and press SELECT again I breifly see on-screen 'PRES OFF'.

Any suggestions how to get into Radio Service Mode? I have a MK3 SW3-1/63.

1. Get in car close doors, turn key to Position 1 or 2.
2. Hit the accept on the Nav system (make sure the radio is off).
3. Pull the key out and put it in Pos 2.
4. Turn radio on
5. Hit "Select" key and hold it until the display changes or flashes and becomes the menu screen.
6. Turn right hand computer knob one position right or left.
7. You are in: You now see the service menu appear with the radio serial number.
8. Use the < > keys to scroll through the functions and the 1 and the 2 keys to make selections for each setting.
