Change the M450 back cover to match the colors of your bike perfectly! You can buy additional back covers in different colors separately.
To change the cover
At the top right corner of M450, put your thumbnail in the groove between the case and the back cover to open the cover slightly.
Using your other thumbnail, open the cover a bit more from the top of M450. Then, lift the cover off.
Place the bottom edge of the color back cover against the bottom edge of M450 (1). Then press the top of the cover until it snaps into place (2).
