Unplug the display from the main harness at the inline Julet Connector. It is located in front of the handlebars.
Using a m3 hex tool remove the bolts from the underside of the button pad and the display brackets.
Spread the clamps of the display and button pad open wide enough to pass the handlebar through. The clamps bend really far without damage as shown below.
Installation of the new display is the steps above in reverse.
Do not overtighten the clamping hardware on the display bracket and button pad. The buttons can jam/be sluggish if the clamping hardware is too tight.
